Connect API - allow to assign Task follower

Connect API - allow to assign Task follower

Business problem:
I have a board for each department.  People in the department can only see their board.  If one department wants to create a task for another department, they cannot create the task on a board they are not a member.  I need a method for a task to be create for another board and allow the task requester to follow the task progress.

Possible solutions:
Use Forms with Flow to capture the information for the task.  Use the connector to Connect in Flow to create the task on the correct board/section.  I need to assign a follower on the task when it is created so the original task requestor can get updates on the task.
