Feature Request: New status icons for in-call and sharing screen

I believe it'd be nice to have these 2 extra status icons:
• In-call - indicate a user is calling another user or is calling on a group chat 
• Sharing screen - indicate a user is sharing their screen

These would be useful so other users would know not to disturb a the user in a call or expect an instant reply if they are in a call. This status would work similar to the in-a-call status from Microsoft Teams.

As for a user sharing their screen, this will be very useful for other users to know that if they message the user sharing their screen, their message will be visible to viewers of that user's stream.
  - this would be different to using the "do not disturb" status, as the user might expect messages from viewers but would not want messages from other users.
 
The status would automatically update when a user joins a call or shares their screen, and has no function other than for other users to see it. This automation may be disabled if the user does not wish to share this status.

Icon ideas:
user in a call
