log
1. Get an account on SupaBase and create a project. Copy key and url.
2. Create a table called 'test' with one entry, and activate RLS with this rule:
CREATE POLICY "t1" ON public.test FOR SELECT USING (auth.role() = 'authenticated');
3. On the Auth/Settings page, disable Email confirmation.
Now you should be able to sign up (once) and you should see the table entry only if you are logged in.
