Cordova Control-media-plugin and bluetooth speaker

Question

I am using cordova-plugin-music-controls 2 and have created a media panel that works correctly. But The app can't handle button presses on the Bluetooth speaker, but handles it in notifications. How do I control multimedia using a Bluetooth speaker?

var data = {
track: 'Test',
artist: 'Test',
isPlaying: false,
playIcon: 'media_play',
pauseIcon: 'media_pause',
prevIcon: 'media_prev',
nextIcon: 'media_next',
closeIcon: 'media_close',
notificationIcon: 'notification'
};
var nxt = 1;
document.addEventListener('deviceready', onDeviceReady, false);
function onDeviceReady() {
console.log("device ready");
mediaNotification();
}
function play() {
data = {
    track: 'Test',
    artist: nxt,
    isPlaying: false,
    playIcon: 'media_play',
    pauseIcon: 'media_pause',
    prevIcon: 'media_prev',
    nextIcon: 'media_next',
    closeIcon: 'media_close',
    notificationIcon: 'notification'
}
MusicControls.create(data
);
nxt = nxt + 1;
}
function mediaNotification() {
    function musicControlsEvent(action) {
        const message = JSON.parse(action).message;
        switch (message) {
        case 'music-controls-next':
            play();
            break;
        case 'music-controls-previous':
            break;
        case 'music-controls-next':
            play();
            console.log("play");
            break;
        case 'music-controls-pause':
            break;
        case 'music-controls-play':
            play();
            break;
        case 'music-controls-destroy':
            break;
        case 'music-controls-toggle-play-pause':
            play();
            break;
        case 'music-controls-seek-to':
            break;
        case 'music-controls-media-button':
            play();
            break;
        case 'music-controls-media-button-stop':
            play();
            break;
        case 'music-controls-headset-unplugged':
            // Do something
            break;
        case 'music-controls-headset-plugged':
            // Do something
            break;
        default:
            break;
    }
}
MusicControls.create(data
);
MusicControls.subscribe(musicControlsEvent);
MusicControls.listen();
}

I have tried using different Bluetooth devices, but there is no result.
