Hotkey for switching workspaces would be nice

I have 3 workspaces in Opera at works and 2 at home. But, other than having the same problem with this post to my new computer at home, now the workspaces' names at work are the names at home and vice versa, while the tabs at each place are still the same - only the names and icons changed. Since I have 2 workspaces at home, and the third one from work popped up with nothing inside, I deleted it yesterday. Today the 3rd workspace is disappear at work with everything inside that I haven't found a way to recover yet, and the name and icon are keep synchronizing (I changed them at home yesterday). This is probably relates to the newer version of opera (started when the Opera account icon appears), because before that workspaces and open tabs worked well. But anyway, how to prevent this without turning off sync for open tabs?

I found myself using Discord a lot, and while it already had a software, I think it would be convenient if there was a Discord shortcut in Opera.
