I tested this & was able to create a My activities dashlet that shows different results depending on who is logged in. I have some reseveration (in this screen and in api explorer) about how difficult it is to enter the contact id when you already know it - but I don't think that is blocking on this.

Looking at the existing dashlet compared to the search-kit created on the other things the built in one does are

• permits the user to choose activity types (multiple) to include and / or exclude
• colour coding on status
• adds single entity actions to the end of the row - note this is not the same as the bulk actions that search kit currently offers as these are (hopefully) already stand alone forms

The above observations are not blocking merge

Patches welcome on the rest :)
