No button? It may already be installed on this device. If not, look for the install icon at the right of the address bar, or open the browser menu and choose Install Dollar Time Machine or Add to Home screen.

Find the Time Machine on your home screen or in your apps.
In Safari, choose File > Add to Dock.
The Time Machine gets its own icon in your Dock and opens in its own window. (Safari 17 or later.)
