Rest API for user creation using other authentication source

Is there a API to create a user using other authentication source as the image? The screenshot (…_other.png) is manually creating a user account using the admin account, and auth0 selected for Authentication Source is OpenID that I enabled for gitea sign in.

It seems like it wasn’t yet implemented as Sep 2020 (Create user in gitea with rest api for authentication source ldap), but hoping it is today.
