I am trying to configure the Azure b2c custom policy to connect to external OIDC (OAuth2) claim providers.
however, this claim provider only supports self_signed_tls_client_auth for token_endpoint_auth_methods. This means when b2c tries to exchange auth_code for a token, it has to use a mutual TLS connection. I couldn't find any documentation on it so leaving my question here for help. thank you in advance.
