How to add ice candidate to the peer?

[qingwa2009]

{"candidate":"candidate:3203880032 1 udp 2113939711 1ab44669-aff7-4bcf-9b58-5eccb72e4375.local 50222 typ host generation 0 ufrag u7EI network-cost 999","sdpMid":"audio","sdpMLineIndex":0,"usernameFragment":"u7EI"}

I use js in browser send the candidate to esp32, but i don't know how to add the candidate to the peer connection! In js i can just use peer.addIceCandidate(candidate).

best regards!
