Audio and Video call integration

Hi,
I have a query to implement video and voice call in one to one chat and conferences. The project is in android and minimum API version support is 21.

I was trying to implement ofmeet in android

implementation (‘org.jitsi.react:jitsi-meet-sdk:2.10.2’) { transitive = true }

I found they support minimum 23 api level. So which could be best way to implement or any alternative library to achieve it.

The highest version which support 2.9.3. Those who suffer these issue like me Please either update minimum os support. for more info please check https://github.com/jitsi/jitsi-meet-release-notes/blob/master/CHANGELOG-MOBILE-SDKS.md
