Start form component - show attachment button

[dzider]

Hi,

I have a start form component where user can attach a file. When the file is attached, a mat-menu-content div appears:

adf-start-form

It has 3 buttons, unfortunately the show button does not work. How can I configure the button so it does something, ideally displays the file?

Alternatively, is it possible to remove menu items?

Thanks for any help!
