Something like a 'thumbs up' icon showing person is agreeing
I feel we should have something similar to a "Thumbs up" icon when on a call where there is one presenter and multiple attendees. It can be used to give presenter a kind of consent that "yes, we agree !". Otherwise it becomes so messy everybody turning their mics on and saying a yes/no or even if we use the chat feature, then presenter needs to switch to the chatbox.
This should be like the Hands Up idea not a chat emoji.
