Track Output window follow track selection

Hello,
I'm using this script to keep the track output window open and changing to the last selected track, and works fine.
Could anyone help me change it so it would;

1.work only if the Output window is open; at this time if the window is closed it opens it;
2: only on any track that start with these words; a loose thing, I guess
" _MUSICA" and " _FX".

Thank you so much

var lastFocusedTrackName;

function main() {
    try {

        var newName = sf.ui.proTools.selectedTrackNames[0];
        if (newName === lastFocusedTrackName || newName === undefined) return;

        lastFocusedTrackName = newName;

        sf.ui.proTools.selectedTrack.trackOutputToggleShow();
        
        

    } catch (err) {
    }
}

function runForever(name, action, interval, timeout) {
    var now = (new Date).valueOf();
    if (now - globalState[name] < timeout) throw 0; //Exit if we were invoked again inside the timeout

    globalState[name] = now;
    sf.engine.runInBackground(function () {
        try {
            while (true) {
                sf.engine.checkForCancellation();
                globalState[name] = (new Date).valueOf();

                action();

                sf.wait({ intervalMs: interval, executionMode: 'Background' });
            }
        } finally {
            globalState[name] = null;
        }
    });
}

runForever("isScrollToFocusedTrackRunning", main, 500, 5000);
