How to make raise/lower your hand with lib-jitsi-meet API (low level)

I want to create raise/lower your hand functionality same as jitsi meet iframe
but in the documentation of lib-jitsi-meet API, I didn’t see any event for this.
so anybody can help me, who I can develop this type of feature using lib-jitsi-meet API (low level)

I already replied here How to make raise/lower your hand - #15 by saghul

@saghul actually I am new with lib jitsi-meet and
I have already seen the answer you send but
how I can manage local track and remote tack with send commands
is there any doc for the send or receive commands?

There is a simple example app on the lib-jitsi-meet repo, I’d suggest you start there.

thanks for the reply
I am done with this functionality using sendCommand
