Include Admin setting to remove external attendees when using the Share Email from Timeline

When using the ‘Share Email from Timeline using Email Assist’ functionality, it would be great to have an Admin setting to automatically  ‘Remove External Attendees’ vs. relying on the team to remember to do so.

Internal emails can mistakenly include external attendees and the CSM may miss the message to remove them. It would be helpful to include a timeline admin setting to automatically remove external attendees when using the Share Email from Timeline.
