According to the OVH docs you can create a service account via oauth2 and then request `/me/api/oauth2/client/{clientId}` to get the identity info. I've created a service account with `authorization_code` flow but when I make the API call I get identity: null in the response.
Does that mean identities only created for service accounts created with `client_credentials` flow? If so, how can I create an identity for my service account?
