edge functionsSUPABASE_URL and SUPABASE_SERVICE_ROLE_KEY which i used via Deno.env.get() to initialize my supabase client in my edge functions.Name must not start with the SUPABASE_ prefix. I tried editing the previously saved keys with that prefix and they dropdown is disabled and hovering over the options says This is a reserved secret and cannot be changed.SUPABASE_ and how can I remove the old ones once i adopt the new strategy?
