How to configure mobile application?

I have installed the Android application for the thinger.io and want to know how I can use to display the dashboard?
I have gone through the mobile application section of the documentation and subsequently Device Token
section of the documentation. But I can not see any QR code which I can use to scan on the mobile application.
On Mobile application I have a black screen with + icon in lower right corner which starts camera to scan the code…

Hi,

Note that the current mobile app does not aim the dashboards, it will show you the defined resources at each device, you can use the PWA feature to “emulate” a native app and you will be able to see the dashboards in a responsive way.

Check this → https://docs.thinger.io/web-console-rebranding#pwa

Hope this helps.
