You just need to define a function called GB:

  global.GB = (event) => {
    switch (event.t) {
      case "musicinfo":
        ...
        break;
      case "musicstate":
        ...
        break;
    }
  };

This would override the GB function if it's already defined, correct? What if multiple apps want to receive events?

Okay, I saw that code in the BG widget and I am using it in my app.
However, I do not know how to trigger it.

The problem is, that I have to read what is playing, when I start the app.
Otherwise I cannot show title information and I do not know what the musicstate is.
```
global.GB = function(j) {
  if (debug ==1) print("global.GB");
  switch (j.t) {
    case "musicinfo":
      musicInfo = j;
      draw();
      break;
    case "musicstate":
      musicState = j.state;
      draw();
      break;
  }
};
```
