Restricting Delete Icon Visibility in DOR for attachment

Summary:

Restricting Delete Icon Visibility Based on Document Type and Role in DOR for attachment

Content (please ensure you mask any confidential information):

Hi,

We are trying to control the visibility of the delete icon (cross mark) on attachments in Document of Records using EL expressions in Page Composer.

Our use case:
Once an employee signs and uploads a legal document, we want to prevent further deletion of that attachment - specifically based on:

The Document Type and role (e.g., employee vs. admin)

Has anyone implemented similar restrictions using EL expressions ? Any guidance or example expressions would be greatly appreciated.
