// Du kannst einen Webhook erstellen der customActivities setzt:
// POST /webhook/set-custom-activity
// {
//   "type": "working_out",
//   "data": {
//     "enabled": true,
//     "activity": "Running",
//     "duration_minutes": 45,
//     "distance_km": 7.2,
//     "calories": 350
//   }
// }
// Dann hier einfach: customActivities.working_out = $('SetCustomActivity').first().json.data;

// WICHTIG: Du kannst auch mehrere Activities gleichzeitig haben!
// customActivities.learning = { enabled: true, course: "Docker", platform: "Udemy", progress: 67 };
// customActivities.streaming = { enabled: true, platform: "Twitch", viewers: 42 };
// etc.
