Activates the custom hostname configuration for a project.

This reconfigures your Supabase project to respond to requests on your custom hostname.

After the custom hostname is activated, your project's third-party auth providers will no longer function on the Supabase-provisioned subdomain. Please refer to Prepare to activate your domain section in our documentation to learn more about the steps you need to follow.
