Any way to know with people is the first to raise the hand

Did there is any way to know witch person raise the hand first ?
It can be interesting to develop a way to know in the chat with is the first person to raise the hand and know witch is the next one

You can implement it using sendCommand() option where you will indicate that you have raised your hand and you can send this command to either all the participants or to moderator and later your moderator or other participant can take action on this raise hand command.

As far as I know, as such there is no other direct Hand which can be raised in Jitsi.

Thanks do you know where to start and how to do it ?

Sir try to capture the hand raise event in your GUI and then use sendEndpointMessage() in the form of JSON which you can parse and implement raise hand.
