> To give you an idea what we are doing; an React Native app that sell and connect a very specific type of workshops with costumers over custom WebRTC Video chat(fork of React Native-based Jitsi Meet). What I can tell, I haven't seen another custom Jitsi-Meet integration yet that gives the ability customize the UI that we have.
I'm sorry I cannot give you advice for your future endeavors, but if your code ends up shelved, please consider sharing your Jitsi Meet customizations with us (I'm one of the Jitsi core devs) so we can improve the SDK.
