Send actionable notifications to an Android device
For each action, you can open an URL, an application on the device or load a lovelace view/dashboard.
If you plan to use a lovelace view the format would be /lovelace/test where test is replaced by your defined path in the defined view.
If you plan to use a lovelace dashboard the format would be /lovelace-dashboard/view where /lovelace-dashboard/ is replaced by your defined dashboard URL
and view is replaced by the defined path within that dashboard.
To pick the application to open, prefix app:// to the the package name.
If the device does not have the application installed then the Home Assistant application will open to the default page.
If you define an action and an URI for a button, URI will take precedence over action.
