Suggestions for mobile sdk/library to use for custom UI

I am looking for suggestion for which mobile sdk/library to use when implementing native app using custom UI. I plan to only use jvb (no jitsi meet) and allow our client to directly interact with the jvb.

Is this even possible?

I have read https://jitsi.github.io/handbook/docs/dev-guide/dev-guide-mobile but it mostly cover solution which rely on jitsi-meet and does not allow the app to control the UI at lower level.
