Scroll down the menu, tap "Add to Home Screen", then tap Add in the top corner.
Android (Chrome)
Tap the menu
Tap the three dots in the top-right corner of Chrome.
Tap Install app
You might see "Add to Home screen" instead — either works.

Tap Install. The app icon appears on your home screen like any other app.
On a computer (Chrome or Edge)
