`OAuth2Session.add_token()` does not exist about authlib

[nfvs]

Sorry it actually exists as a property, but it was returning None:

    @property
    def add_token(self):
        if not self.token:
            return None

        token_type = self.token['token_type'].lower()
        if token_type == 'bearer':
            return add_bearer_token

I followed the docs and had token_type="oauth1.0", which was making that function return None.

@nfvs OAuth2Session is designed for OAuth 2. Currently, it only supports bearer token.

I followed the docs and had token_type="oauth1.0"

Where did you find this in the documentation? It must be a mistake.

Are you trying OAuth 1? Then you should use OAuth1Session.

I'm using OAuth 2 actually. My mistake, the model only has OAUTH1_TOKEN_TYPE = 'oauth1.0': https://docs.authlib.org/en/latest/client/frameworks.html#cache-database

I'm storing the tokens in flask's session cookie, right after calling authorize_access_token(), and then in fetch_token I was just hardcoding a token_type.

@nfvs It is not safe to store a token in session cookies. If you are just doing it for testing, that's ok.
