Feature: All Talk Attendees to Add Name When Entering New Call

[stownsend101]

Is your feature request related to a problem? Please describe.
Meeting request is shared, attendees join call and aren't asked to edit name, appearing as 'Guest'. Difficult to identify in conversation.

Describe the solution you'd like
All attendees, who do not have a Talk account, are asked to update name on hitting 'Start Call'.

Describe alternatives you've considered
Name attendees as moderator - but this will take too much time.

Additional context
No.
