I'm working on a bot participation handler to automate a task.

For this to work, a photo with a comment is required.

The bot does see a "message_created" operation, but it does not trigger a "message_edited" when a photo with a comment that has been posted previously, has been edited. It does not trigger either when the checkbox "notify members" has been checked.

Since it happens often that the photo gets posted and later edited, this makes it impossible to fully utilize the participation handler.

Is there a way to watch the photos/attachments for edits or can a trigger for this be added?
