OAuth Tutorial Confusion

I'm setting up Google OAuth but having issues with Supabase. Basically, Step 6 (on https://supabase.com/docs/guides/auth/social-login/auth-google?queryGroups=platform&platform=web&queryGroups=environment&environment=client#application-code) is saying to place your Redirect URL as the web site your sign in button appears (?) which in my case because I'm developing locally is
http://localhost:3000
http://localhost:3000
however I'm getting
Error 400: redirect_uri_mismatch
Error 400: redirect_uri_mismatch
, I'm assuming there's something I'm missing here?
