[Google] Not possible to provide extra config for authorization

[harlan-zw]

When authorizing with google, these params are hardcoded

response_type: "code",
client_id: config.clientId,
redirect_uri: redirectUrl,
scope: config.scope.join(" ")

However, several other options can be provided here. See https://developers.google.com/identity/protocols/oauth2/web-server#httprest_3

What is currently blocking me is access_type that allows you to specify offline, which is the only way to get a refresh_token, which is the only way to keep the user logged in for more than 1 hour (when they need to access Google APIs).

Maybe an option like useRuntimeConfig(event).oauth.google.authorizationParams

config: {
    redirectUrl: '/auth/google',
    scope: [
      'https://www.googleapis.com/auth/userinfo.email',
    ],
    authorizationParams: {
      prompt: 'consent',
      access_type: 'offline',
    },
  },
