Show the meeting name and attendees while you are waiting in the lobby
Often, I join a meeting a few minutes early and use the time to check email, update notes, etc.
Currently I sit in the lobby or with the "Waiting for others to join. . ." message.
It would be nice Teams displayed the meeting you were waiting to start, time, agenda, attendee list, etc. so you could have a bit more context and were ready for when the meeting started.
I currently have to join the meeting, then go back to my calendar to grab that info while I wait.
