No "Sync Devices" option in desktop extension

I am testing out the mobile app and trying to follow the desktop sync instructions. Step 2 says to find “Sync Devices” in the settings, but I cannot find this option in the 1.5.1 version of the extension.

Have you been following the instructions in the email? The UX is in the extension is not yet like the final version. The email is laying out all steps.
