Catch Event "onClick" of Sign In Options?

[awitherow]

Is there a callback that I could hook into for any of the sign in options?

I would like to be able to set my UI to loading while the login and redirect process occurs on the private route switching example.

Idea: in uiConfig.callbacks add onAuthAttempt or something similar, a callback function that has the param choice or something similar available.
