Apple just released a new support video on their Youtube Channel, which explains how you can use the Find My app to help locate lost devices, search for compatible items like keys with an AirTag attached, and share your location with friends.
If you’ve lost an Apple device or personal item, you can use the Find My app on an iPhone, iPad, or iPod touch or a Mac with the latest version of macOS that is signed in with the same Apple ID to locate it.
For a lost iPhone, iPad, iPod touch, Apple Watch, Mac, AirPods product, or a compatible Beats product, you can also use the Find My app on a device owned by someone in your Family Sharing group or log in on iCloud.com. / search in a web browser.
