NEW Host object in Power Apps will provide information about the current host running the App
The Host object in Power Apps provides information about the current host running the app.
„Similar to a control or the App object , the Host object provides properties that identify information from the host running the app. Every app has a Host object.
Note The host object is currently only available in custom pages and canvas apps.To access the Host object, expand the App object at the top of the Tree view pane and then select it. In this example, the Host object doesn't have any properties that accept formulas.“
