accessing session user in validate_silent_login

[dopry]

I'm working on implementing silent login on Django. The documentation says...
per https://oauthlib.readthedocs.io/en/latest/oauth2/oidc/validator.html#oauthlib.openid.RequestValidator.validate_silent_login
,

Ensure client supplied user id hint matches session user.
If the sub claim or id_token_hint is supplied then the session user must match the given ID.

Normally in Django the session user is looked up by middleware and accessed via request.user. When the OAuthLib.common.Request is created the user is not preserved. Is there a recommended way to add the session user to the OAuthLib.common.Request?
