[DUMMY CODE, NOT TESTED] Utopiah BestRoom script with scenes

gistfile1.js

// Warning this is pretty hacky as you need to change the URL for the room to end with the scene ID. Maybe there is a better way to query the scene ID based on the url, but the spoke only allows to set URL so this is what I imagined late in the evening.

// open-media-button.js
} else if (await isHubsRoomUrl(this.src)) {
   // Get the 6 last letters of the name of the url (that you set up as the Scene ID)
   let lastSix = this.src.substr(this.src.length - 6); // Should be something like "avC5IO"
   // use modified Utopiah script
   let bestRoom = getBestRoom(lastSix);

   await exitImmersive();
   location.href = bestRoom; // because getBestRoom returns the bestRoom.url already
} else {


// Wherever you want, probably somewhere above the code in the same open-media-button, or in its own file (remember to import it!)
// Get the URL of a Hubs room that is not empty nor at room capacity
