Sharedrop keeps loading after deployment

I think I might have done something wrong, as I'm not familiar, with the firebase db. I created a realtime db, copied the link shown under the "Data" tab and put it in the FIREBASE_URL env. I changed the rules to this:

{
  "rules": {
    ".read": true,
    ".write": true
  }
}

[Sign up](https://www.firebase.com/) for a Firebase account and create a database.
Go to "Security Rules" tab, click "Load Rules" button and select firebase_rules.json file.
Take note of your database URL and its secret, which can be found in "Secrets" tab.

I think some things might have changed on the firebase side as I couldn't find "Load Rules", just a Rules tab. The "Secrets" tab I couldn't find that either. I guess it's all within the Rules editor now?

I put nothing in the FIREBASE_SECRET env (for testing). Unfortunately I don't see any logs of not being able to connect to a firebase db. So I'm not sure if it connects or not.

Can someone tell me what I'm doing wrong?
