AI custom model does not appear in digital workspace

Hello guys,

I'm trying to create my own AI model by
https://docs.alfresco.com/intelligence/concepts/custom-config-textract.html

I followed the documentation and checked it several times, created a custom AI content model, model context, property mapping, updated the share-config-custom.xml and digital worspace json file. No error in logs.

Unfortunately, the digital workspace does not display custom metadata. I must have missed something. Could you give me some advice?

I want to extract text from pdf invoices using AWS textract. I've started default recognition (e.g AI Text Lines, AI Dates aspects working) and try to add a custom model.

1) My custom model

<?xml version="1.0" encoding="UTF-8"?>
<model name="my:contentModel" xmlns="http://www.alfresco.org/model/dictionary/1.0">
    <description>Custom Content Model for Artificial Intelligence extension</description>
    <version>1.0</version>

    <imports>
        <import uri="http://www.alfresco.org/model/content/1.0" prefix="cm" />
        <import uri="http://www.alfresco.org/model/dictionary/1.0" prefix="d" />
        <import uri="http://www.alfresco.org/model/site/1.0" prefix="st" />
        <import uri="http://www.alfresco.org/model/system/1.0" prefix="sys" />
        <import uri="http://www.alfresco.org/model/ai/1.0" prefix="ai"/>
    </imports>

    <namespaces>
        <namespace uri="http://mymodel.org" prefix="my" />
    </namespaces>

    <aspects>
        <aspect name="my:invoice">
           <title>Invoice Info</title>
           <parent>ai:textract</parent>
           <properties>
               <property name="my:varsymbol">
                   <title>Variabilni symbol</title>
                   <type>d:text</type>
		   <multiple>true</multiple>
                   <index enabled="true" />
               </property>
               <property name="my:splatnost">
                   <title>Datum splatnosti</title>
                   <type>d:text</type>
                   <multiple>true</multiple>
                   <index enabled="true" />
               </property>
	       <property name="my:ico">
                   <title>ICO</title>
                   <type>d:text</type>
                   <multiple>true</multiple>
                   <index enabled="true" />
               </property>
               <property name="my:dic">
                   <title>DIC</title>
                   <type>d:text</type>
                   <multiple>true</multiple>
                   <index enabled="true" />
               </property>
           </properties>
        </aspect>
    </aspects>
</model>

2) AI property mapping

{
   "keyValueMapping":[
      {
         "aiTextract":[
            {
               "key":"Variabilni symbol:",
               "aspect":"my:invoice",
               "property":"my:varsymbol"
            },
            {
               "key":"Datum splatnosti:",
               "aspect":"my:invoice",
               "property":"my:splatnost"
            },
  	    {
               "key":"ICO:",
               "aspect":"my:invoice",
               "property":"my:ico"
            },
            {
               "key":"DIC:",
               "aspect":"my:invoice",
               "property":"my:dic"
            }
         ]
      }
   ]
}

3) Update app.extension.json for digital workspace

"content-metadata-presets": [
      {
        "id": "app.content.metadata.custom",
        "custom": [
          {
            "id": "ai.metadata.features",
            "title": "AI Data",
            "items": [
              {
                "id": "ai:products",
                "aspect": "ai:products",
                "properties": "*"
              },
              {
                "id": "ai:dates",
                "aspect": "ai:dates",
                "properties": "*"
              },
...
	      {
                "id": "my:invoice",
                "aspect": "my:invoice",
                "properties": "*"
              }
...
            ]
          },

3) Update share-config-custom.xml

<?xml version="1.0" encoding="UTF-8"?>
<alfresco-config>
    <config evaluator="string-compare" condition="DocumentLibrary">
        <!-- Aspects that a user can see -->
        <aspects>
            <visible>
                <aspect name="my:invoice"/>
            </visible>
        </aspects>
    </config>
</alfresco-config>

4) add rule and aspect to folder

And this is the result:
