Device flow qrcode

[trumanbutter]

Calling client.deviceAuthorization(params) we're successfully resolving the promise which is great.
When we log the response to the console we can see a bunch of key value pairs

DeviceFlowHandle {
  device_code: ''
  expires_in: 300,
  interval: 5,
  user_code: '',
  verification_uri: '',
  verification_uri_complete: '',
  verification_uri_complete_qrcode: ''
}

The one I'm curious about is verification_uri_complete_qrcode which returns a base64encoded string. When I try to reference it directly it's undefined.
Looking through the DeviceFlowHandle class -> index.d.ts there's no reference to verification_uri_complete_qrcode

export class DeviceFlowHandle<TClient extends BaseClient = BaseClient> {
  poll(options?: DeviceFlowPollOptions): Promise<TokenSet>;
  abort(): void;
  expired(): boolean;
  expires_at: number;
  client: TClient;
  user_code: string;
  device_code: string;
  verification_uri: string;
  verification_uri_complete: string;
  expires_in: number;
}

Does openid-client support this value?

It's a proprietary, non-standard response property, it cannot be a part of the type definition.

Ok, I see that makes sense.
