SuperOffice for Outlook on Mac

Hi!

I would like to add Super Office to my private Mac. I have downloaded Outlook and SO Web Tools, but unfortunately it doesn't seem to work to download SO add-in for Outlook. In the Outlook app store, I download the SO for Outlook add-in, log in with my job credentials but then while downloading/installing I get this message: "Taking you to Microsoft 365 to complete this process." Nothing happens and this keeps spinning for hours. If I click on the cross, the add-in is still not downloaded and I cannot for example open emails from SO into the outlook app or save emails into SO. 

Please someone tell me if it's even possible to work SO for Outlook on a Mac (Macbook Air M1 with latest software update) so I can go to using 1 computer instead of needing the Windows computer for sending & saving emails
