Implicit Flow does not work about omniauth_openid_connect HOT 1 OPEN

I have investigated this problem.
The omniauth/omniauth_openid_connect repository version accepts only code and id_token as response_type.
In the Implicit flow, the id_token makes the IdP return only the id_token as the authentication response. It works correctly only with some IdPs that return it extended from the specification.
For example, Azure AD adds additional fields that identify the user, such as an email address.
However, Yahoo JAPAN, which strictly meets the specifications, does return only minimal fields as the authentication response, and the client must request the user information using the access token.
For such IdPs, you must specify ['id_token', 'token'] as the response_type. So, omniauth/omniauth_openid_connect should be able to accept it as the response_type.
