I don’t know… my desktop is super old, I had to go with OpenVPN instead.
Assuming you have a Mac, not having WireGuard in your Applications folder may be an issue, since that is were apps are activated… Here is the video for Mac OS maybe it would help… WireGuard Installing On Mac OS - YouTube
Near the end of the video, you will see how you can control your VPN from WG’s logo on the top right corner.
If you get frustrated with WireGuard like I did, remove it from the server with the script you used, remove the apps from the phone and desktop. Switch to OpenVPN with the OpenVPN script from Nyr.
I am very happy with OpenVPN’s client interface, easy to setup and use, a better choice for a newbie like me.
In either case, I hope to hear good news from you soon!
