I have a pretty standard workflow and status transition where a ticket that is in progress is triggered to move to Code Review upon a PR in github being merged into master.
I am trying to find a way where if that transition is completed by the trigger then a comment is posted "This issue will be available for testing on staging shortly"
I don't want it to be a post-validation set up as there will be some manual transitions that I would want the user to leave a comment manually for.
