Open synced tabs from other devices


I was able to sync 3 browsers in one keychain: Windows, Mac and Android. Selected sync all items in all three browsers. All three see each others’ device names in sync settings.

I can see some of the most recent history to appear across devices, but i cannot find a way to see open tabs or select to manage other devices.

Are there instructions published somewhere, how to actually open tabs (not history) from other devices?
