[keycloak-dev] GroupMembershipMapper with ID

Hello Keycloak Devs, We need a mapper for oidc which maps the ID of a group. We are wondering if the GroupMembershipMapper, which maps the name of a group, could be made configurable to map one of Name, Full Path, or ID. Or would it be better to create a new mapper type? The difference between these mappers would be minimal. Best regards, Rafael
