We have recently starting having our daily team meetings ("huddles" in the Lean vocabulary) virtually. We all join the meeting via our laptops. One frustration a few people have mentioned is not knowing when they can say something. Is there a "beep" or "chime" that people can use to say "I want to speak now"? If there is not one in Teams, is there something external that people can use? There are other methods (raise your hand, say "question" and your name, leave enough space after each topic for feedback), but we wonder if there is a technological solution to this problem.
