DisplayIncomingCall UI is not working in Android.

Bug report

• I've checked the example to reproduce the issue.

• Reproduced on:

• Android

• iOS

Description

I have integrated RNCallKeep as per the guidance specified in repo, It looks strange that it is able to show displayIncomingCallUI on iOS, however it seems to be not working in android. it seems so strange that the code is similar which means, when we replicate the code as per the demo, it should work irrespective of the platforms. How come it won't work for android, even after following setup instructions and demo example. Can anyone help me where I am committing a mistake.

Steps to Reproduce

Code

const options = {
      ios: {
        appName: "Sovereign Wallet",
      },
      android: {
        alertTitle: "Permissions required",
        alertDescription: "This application needs to access your phone accounts",
        cancelButton: "Cancel",
        okButton: "ok",
        additionalPermissions: [PermissionsAndroid.PERMISSIONS.READ_CONTACTS]
      },
    };

    try {
      RNCallKeep.setup(options);
      RNCallKeep.setAvailable(true); // Only used for Android, see doc above.
    } catch (err) {
      console.error('initializeCallKeep error:', err.message);
    }

    RNCallKeep.addEventListener('answerCall', this.onAnswerCallAction);
    RNCallKeep.addEventListener('endCall', this.onEndCallAction);

Displaying like this when on a push notification
RNCallKeep.displayIncomingCall(this.getCurrentCallId(), "XX Name", 749nsusd7b, "",true);

Start with the repository example and the Android setup instructions, then trace the RNCallKeep.setup, setAvailable, and displayIncomingCall entry points using the reported CallKeep 3.0.12 and React Native 0.59.9 versions. Reproduce on Android with logs captured; done when the cause is identified and displayIncomingCall shows the incoming-call UI or the required setup correction is documented.
