In a room of 4/6/8... users come one by one.

When there are less people, the seats are empty and eat up the screen space.

However, in the booth, while it allows 8 seats. when there are less people, the screen is optimized for the guests inside.

Can we have the same logic in the booth

Always add 1 seat- "Waiting for more guests to Join", unless its the last seat.
