How to differentiate RTCPeerConnection between Jitsi's conference and Jigasi?

I create customized WebRTC and build my own electron, I add some flags in my WebRTC that could be set from a parameter of the new RTCPeerConnection(). I would to know which RTPPeerConnection was created by Jigasi and the original Jitsi’s Conference because I want to set different parameters for them. Is it possible? It would be really helpful if I could know where I should modify it. Thank you.

Jigasi signalling for sip and xmpp you can find in GitHub - jitsi/jitsi: Jitsi is an audio/video and chat communicator that supports protocols such as SIP, XMPP/Jabber, IRC and many other useful features. and the media handling in GitHub - jitsi/libjitsi: Advanced Java media library for secure real-time audio/video communication.
