How to add prompt settings to Google OAuth?

[justinforlenza]

I am attempting to add the Google OAuth "prompt" parameter so that a user is asked to choose an account even if there is only one, giving them the option to enter a new account.

I added "prompt" into my config object however the OAuth2Provider appears to just ignore it.

Google Documentation on Additional Parameters:

// Your can use custom parameter.
provider.on("before-authorize-request", parameter => {
parameter["XXXX-Hoge"] = "hogehoge"
})
