DMSS app DAHUA

Third party integrations
1

Hi,
I successfully integrated my Dahua VTO Doorbell into Home Assistant.
On iPhone/iOS I use the HA app and also the Dahua one (DMSS to answer to the doorbell when it rings).
Because the DMSS push is total crap (it rings after minutes when somebody rings the doorbell) I’m pushing the singal to the HA app and then rise a notification in iOS.
It works, I also can click to open the DMSS app to answer but it opens in the home page and not directly the doorbell.
Does anybody know the app url syntax to open the specific doorbell from the notification?
The missing part after url: dmss://

Here the code:

action: notify.mobile_app_iphone
data:
  message: Somebody rings...
  title: Doorbell
  data:
    url: dmss://
    push:
      sound:
        name: US-EN-Daisy-Front-Door-Motion.wav
        critical: 1
        volume: 1
