To use this endpoint, the user is required to have the ProjectWise Forms Comment (
Forms_CommentAccess) permission for the project, or for the issue's associated form definition if form definition security is specified. (Having Create/Modify, Assign, Approve, or Full permission automatically grants the Comment permission as well.)
