Shelly wall display xl now has an HA app - but is this better?

Configuration
1

Up until the latest firmware upgrade, the shelly wall display XL, had the option to configure the URL of your home assistant dashboard, and it would load it on the screen. In home assistant's configuration.yml you could add this entry, to make it not require a login, since the display and HA are on the same network

homeassistant:
  auth_providers:
    - type: trusted_networks
      trusted_networks:
        - 192.168.10.0/24
      allow_bypass_login: true
    - type: homeassistant

You could then use browsermod and wallpanel to automatically make the dashboard full screen by adding this in your dashboard.yml

wallpanel:
  enabled: false
  profiles:
    device.browser_mod_cc810c4b_d9b2fecd:
      enabled: true
      fullscreen: true
      hide_sidebar: true
      hide_toolbar: true
      idle_time: 0
      alert_errors: false

It was working perfectly!

Now shelly decided that they will remove the browser from the wall display xl, and replace it with an actual home assistant app you can download.

But now the app simply opens at the default (overview) dashboard and of course its not full screen.

I really want to make it like it was before.

Is there a way to open my custom dashboard on HA load, and also make it full screen?
