Use my own server for Jitsi meet conference

I have set up Jitsi on my own server on a domain like https://mydomain.com

Now, I plan to integrate Jitsi conference on Android and iOS through this url instead of meet.jit.si which is the default url.

I am invoking the following code in my Android application to make this possible:

     val serverURL: URL
        try {
            serverURL = URL(getString(R.string.jiitsi_url))
        } catch (e: MalformedURLException) {
            e.printStackTrace()
            throw RuntimeException("Invalid server URL!")
        }

        var userInfo = JitsiMeetUserInfo()
        val options = JitsiMeetConferenceOptions.Builder()
            .setServerURL(serverURL)
            .setWelcomePageEnabled(false)
            .setUserInfo(userInfo)
            .setRoom("1")
            .build()

        JitsiMeetActivity.launch(activity, options)

But, instead of going to the url defined in jiitsi_url above, it is going to http://meet.jit.si/1

Is there anything else that is required to point to my own Jitsi domain?

Thanks,
