Solved Purchased Join, Do I also Have To Purchase Windows App?

Finally went ahead and bought Join. I used the Chrome browser extension quite easily so that was great. However I discovered there is an actual Windows app that cost $1.49. Is this app included or a separate app?
This would be ideal for me cause I am already running a lot of Chrome extensions, to use a dedicated Windows app would be much better.

Thanks.

 

Yes you have to buy the windows app separately.

That does make sense.
