Allowed Origins

I am using supabase via lovable. I am getting lots of issues with Google OAuth and Email OAuth. I have asked you AI as i think one of the many issues is that i one site linked to supabase. The AI bot told me to go to Allowed Origins in Authentication / Settings. I am unable to locate "Allowed Origins" - I am on the free service. Can someone point me in the direction to find this.:supafire:
