PhoneTrack installation on Pc Help

Good morning, I wish I could use the PhoneTrack app, if I understand correctly, besides installing the app on my phone, I also have to install it on my Nextcloud server. Since I don’t have a Nextcloud server, I registered with the provider Webo. Here appears the entry PhoneTrack, but if I click nothing, I guess because first I have to install the app on PC, so I downloaded it (phonetrack-0.7.2.tar.gz) from the Store, but I don’t know how or where to install it. Can anyone kindly help me? Thank you so much
