From navigation items you can only jump to a) microflows, b) forms that know how to retrieve their data themselves. A form with a data view cannot be used as a navigation target because it does not 'know' which object to show.
The solution is to let the navigation item point to a microflow that retrieves the object you are interested in and then shows in the form with the data view. The 'Show form' activity in microflow lets you select an object to pass to the form. You will need to create an actual object of the given entity before you can retrieve it. This is something you might want to do in a separate form.
