Is there a way to launch a mobile app?

Hi,

I would like to know if it is possible to have an icon who open an app of the smartphone (when used from ha mobile app)

Regards

Android intet is possible through the companion app.
But not sure if it works as you expect.

I’m on iOS.
I’ve a connected device who have no integration with ha, so what I would like is to add an icon in ha who simple launch the app of my device.
