There is no trash icon when one select the comment to remove it.
Hi Serge Jasmin , and Welcome to the Canvas Community!
The trashcan is at the upper right corner............
I hope this helps,
Hi, Serge Jasmin Welcome to the Canvas Community! I believe Kelley has directed you to the trash can icon you can use to delete conversations and messages; however, as you rightly note, when the view is toggled to Submission Comments, the trash can icon does not appear. Submission comments can be deleted from the SpeedGrader for the assignment, but currently cannot be deleted from the Canvas Inbox, so this idea is open for voting.
