Oauth implicit flow with Meteor

Hi,

I’m trying to implement a package for oauth login based on service that only supports Implicit Flow from now.

In consequence, there is no possibilities for the server to get the access_token considering it is only available client side and must be parsed from hash.

Is there any way to use implicit flow with the current state of the oauth package from Meteor or is it only OIDC based ?
Moreover, is there any actual documentation for creating custom oauth provider with Meteor ?

Thanks for your answer,
