Find my Phone as a shortcut
I have a family iCloud plan, and everyone is on the list. So I saw the option in the Shortcuts app that mentioned that I can add it as a shortcut.
If you go into the Shortcuts app and look under the Gallery tab, you might see an topic to add to &quot;Show the location of&quot; for your wife's phone.
But I think you can also directly just ask Siri to find your Wife's phone. I've done that with my oldest daughter's phone sometime as well.
