Issue Summary

Comment field Required while changing assignee inside a ticket

Expected Results

When User A changes the Assignee field to "Unassigned or to User B", We need a feature to make the comment mandate during these changes.

Actual Results

There is no direct way to make these changes via Workflow.

Workaround

Required, if there is no workaround please state: Partially we can make it work via Automation.

Eg: If the assignee is changed and if he has not added the comment, then the case will be assigned back to him asking to write a comment based on this changes? 

However we cannot restrict the user from Assigning the case from A to B, But again if the comment is not added then the ticket will be returned back to him.
