planner comment delete edit
It is more convenient for Planner's Task Comment to be able to delete or edit, it like Teams's conversation and chat.

+1, Trello allows this as well
I receive notifications of comments in my desktop Outlook application, under groups.
When I delete notification of a specific comment, it also deletes the comment on that specific Task in Planner.
This is actually a problem in some cases, but also a way to delete a comment on a Planner Task.
