[Help] Sacrilege: I need help with KDE Connect under Windows.

Hopefully this is the right community to ask this question in.

I have been tasked with providing a way for a small team to send and receive text messages via a real mobile phone from their computers. Having daily driven Fedora since 2017, my first thought was KDE Connect SMS. Unfortunately, I have to be able to support Windows in this endeavour.

As such, I have three questions:

• KDE connect is available for Windows, however as far as I can figure kpeoplevcard is not. Am I mistaken? Is there a way to get contact names syncing successfully in a Windows environment, even just one-way?
• Despite the notification permission being granted on Android, incoming text messages produce no notification on Windows. I have read this may be a fault that occurs when the Android client was installed from F-Droid. Is this the case? I haven't made a Google account for this device, so perhaps I need to do that and install the Play Store version.
• MMS images appear fine in the KDE Connect SMS application, however they are only thumbnail sized and can not be saved as a file or copied. Can they at least be made bigger, if not exported?

I'm worried that KDE Connect may not be the correct choice for this use-case if these issues don't have workarounds. I may have to use Google's Messages for Web, but that doesn't allow concurrent connections from multiple PCs like KDE Connect does - and it will mean I have to deal with Google.
