Is Jitsi externalAPI only for web applications? (If not, how can I use it in my Android app)

Hello, I am integrating Jitsi to my Android application. I want to use the externalAPI’s methods like setPassword. But I dont know how to use it. Is it only for web application?
If I can use it on Android, how to start?

The external API is designed for web applications. On Android we have the Jitsi Meet SDK: https://jitsi.github.io/handbook/docs/dev-guide/dev-guide-mobile

There is the option of getting the number of participants or setting a password in the External API. How can I do these in the Android applciation then? Because I did not see these options in Android SDK.

Those are not yet implemented.

Thank you. Well, is there a way maybe I can try to implement these?

Can I start from a point that would be helpful for these?
