How to use the aiogoogle.auth.creds.UserCreds function in aiogoogle

        scopes = json_res.pop("scope").split(" ")
        user_creds = UserCreds(**json_res, scopes=scopes)
        # Idk why, but sometimes google returns these json params empty

            self["token_endpoint"] if user_creds.get("token_uri") is None else None

        )
        user_creds["expires_at"] = self._get_expires_at(user_creds["expires_in"])
        return user_creds
