[PP-1] Revision UI for ECK after revision support is added

Generic Revision UI has been implemented in ✨ Implement a generic revision UI Fixed within core which has made possible to implement Revision UI for ECK revision support. Refer #2788507-116: Add revision support → for the patch.

I propose we just add this in ✨ Add revision support Closed: duplicate since it allows us to get rid of a lot of custom code that's being added there.
