Keycloak configmap make user fields required

Hi,
I would like to make some of the fields of the user required. Specifically Email, First Name, and Last Name.
Looks like username is required by default.

We are deploying keycloak in kubernetes and have a configmap yaml file with all the current settings.

Can anyone point me to the documentation or tell me which setting or how to make the fields required?

Thank you,
Michaela
