SugarConnect Installation - is there a way to install directly to outlook 365 desktop?

We are planning to test two licenses but after purchasing them the instructions and microsoft seem to not be on the same page.  I have no way to add the "App" in outlook 365 online it is not there.  I was hoping there was a way to download or get a direct link to install this so we can begin to work.  It seems easier to load into gmail but our entire team works on the desktop version of outlook 365.  

Any advice is appreciated.
