Create import json file with client that has service accounts role

Getting advice
1

I’m trying to make a json import file that will include the client with Service Accounts Roles to manage users and realm.
realm-management manage-users False ${role_manage-users}
realm-management manage-realm False ${role_manage-realm}

Where can I find examples of such an import?

I’m using keycloak 23.0.7 and 24.0.4

Thanks
