Supabase

Hey everyone, I've been excited to try out realtime + RLS on a side project for a while and finally digging into it. I'm using hosted Supabase but no matter how much I dig through the docs, I can't find a reference for which websocket URL to use for my project. Probably obvious, but could anybody point me in the right direction? Thanks!

Further to this, I found a reference to the following structure: 

ws://<projectID>.supabase.co/socket

The Javascript SDK builds the realtime url this way:
this.realtimeUrl = `${supabaseUrl}/realtime/v1`.replace('http', 'ws')

so it is ws://<projectID>.supabase.co/realtime/v1

Thanks for your reply <@!320816942736736258>, but unfortunately that doesn't work 😦 

```
const client = new RealtimeClient('ws://<projectID>.supabase.co/realtime/v1');
client.connect();
```

Yields:

```
WebSocket connection to 'ws://<projectID>.supabase.co/realtime/v1/websocket?vsn=1.0.0' failed
```

(Obviously I'm replacing my ID, just keeping them out of chat for now :))

When I pass `{ params: { apiKey: jwt } }` (where `jwt` is a valid client JWT), the same thing happens.
