Alternatives to the `link` SSO field of Commento?

https://docs.comentario.app/en/configuration/frontend/domain/authentication/sso/non-interactive/#payload

I noticed the link field was not available compared to Commento, are there any alternatives to it? Or do you have any plan to add it back?

One alternative solution I can think of is to add a URL prefix or template to the domain config, and build the profile link with the user name.
