This is not official Jitsi. It’s the work of a Developer using Firebase to extend the capabilities of vanilla Jitsi.

do you have other solutions for implementing breakout rooms also?

It’s a very complicated feature and not yet available. If you have very advanced skills you can help Jitsi developers who seem to work on this as a high priority feature.
