Define Oauth2 authentication Object

[arthurharrison]

I might be doing something wrong, but I could not find a way to define the Params object. For example, the default uses username, password, client_id, client_secret, but instead, I just wanted an object with email (instead of username) and password beign passed. Is there a way to define it?

Thank you very much <3
