Windows 7 support

Guys, I have a few machines running Windows 7 SP1 x64, with Net 4.8 and WebView2, yet Focalboard refuses to launch. Yes, that OS is out of Silicon Valley favour, Microsoft hegemon urges to spend time and money for software and hardware upgrades I do not need, but frankly could not care less because it works.

So what sauce do you have under the hood that requires Windows 10 specifically? Or it is just a matter of compilation flag? If it's about the latter, then please consider adding that flag to make more people productive beyond the so-called golden billion.
