Your website is a monster where is very difficult to get the useful information.

I wanted to use Realm to use a mongo cluster and after hours trying I give up.
I couldn't connect to the cluster after I created serveral ids (app, api, another api id, ...)

Solution: Let's say I have a single cluster and a single realm app created.
Just give me the code with all the ids necessary.

In my case I wanted to run it from the browser.
This is the code I tried to execute:

    const app = new Realm.App({ id: 'tradeapp-bozmd' });
    const credentials = Realm.Credentials.apiKey('51f080c1-f0f7-41de-a69c-9a408db76e57');
    // Authenticate the user
    const user = await app.logIn(credentials);
    // `App.currentUser` updates to match the logged in user
    console.assert(user.id === app.currentUser.id);
    this.db = user.mongoClient('mongodb-atlas').db('TradeTeam');
    console.log("this.db :", this.db )

One of the issues was that I couldn't find anything about Realm inside cloud.mongodb.com. I had to search on internet (gpt told me about Realm). Terrible.

Simplify your website. What a terrible design.
