With the 2023 Release Wave 2, as per Microsoft Documentation, we can pin activities such as records to the top of the timeline.
We could see that option available for the Notes in the timeline.
It also shows the number of records pinned.
To unpin it, we need to click the icon again, and the record will move to its original position.
Hope it helps..
how to enable pin for required activities in timeline?
