Introductions button to raise participants hands to indicate they have not introduced themselves yet

Is your feature request related to a problem? Please describe.

It seems like often times it’s difficult to keep track of who has introduced themselves near the end of a brief round-robin introductions.

Example:
Andrew: “I am Andrew, blah blah, and I’ll choose… Katy to go next”
Katy: “I’ve already gone”
Andrew: “Okay umm… how about…”

Awkward silence

Moderator: “If anyone hasn’t gone please just volunteer”

Describe the solution you’d like

A button that raises all of the participants “hands” to indicate that they have not introduced themselves yet. Once a participant has introduced themselves they can lower their “hand”

Describe alternatives you’ve considered

Everyone raises their own hand.

Additional Context

Could be a problem with participants who join late.
