Folder Icon Disabled on List Page for Custom Entity in On-Site Version

Hi everyone,

I'm using the on-site version of Creatio and have created a custom entity. However, I've noticed that the folder icon on the list page is disabled for this entity.

Has anyone encountered this issue before? What could be the possible reasons for this behaviour, and are there specific settings or configurations I should check to enable it?

Any guidance would be appreciated!

Thanks in advance.
