Hi all! I want to create some type of user groups in Kratos to use them in Hydra. Is there a way to implement some sort of internal account linked to the user (or multiple users) in Kratos? I want to issue tokens that won't be invalid once the user is deleted. So it would be great if I could somehow create an identity in the Kratos and on user login I would give a Hydra token for the user's internal account associated with it. Or could this be implemented in the self-hosted UI/consent UI side changing user_id o internal_user_id in the token that being issued?
