ACS Community 6.2 pdf viewer does not show digital signature on pdf document

Is it possible to set the 201911GA pdf viewer to show the digital signature? 4.2.f community showed it.

Now on the small thumbnail there is there the digital signature (bottom right corner):

If we download the original via ACS the signature is visible.

Alfresco pdf converter config:

alfresco-pdf-renderer.root=/opt/alfresco-6.2.0/alfresco-pdf-renderer
alfresco-pdf-renderer.exe=/opt/alfresco-6.2.0/alfresco-pdf-renderer/alfresco-pdf-renderer

Transform services (is it related?):

Spoiler
transform.service.enabled=false
local.transform.service.enabled=false
legacy.transform.service.enabled=true

Document Preview framework changed from 4.2.f (Flash) to 5.0 (pdf.js).

Since pdf.js doesn't support digital signature preview (https://github.com/mozilla/pdf.js/issues/1076), Alfresco is not displaying this field in Share.

It should be worthy to add this feature to the product.

You could open a ticket with this request in https://issues.alfresco.com

Registered and tried, but was unavailable. Problem with a field (not marked which), correct it or contact administrator for check the log.

Jira is more inhumane than our OTRS, quite the feat.

As far I know, it is possible with a minor modification. Check the following link for modifying pdfjs properly:

Kind regards.
