How can my C# Windows Runtime Component install the WebView2 Runtime?

Question

Pretty simple question. I know how to find out if it's been installed. But, if it hasn't....how do I install it? All of the documentation appears to be geared towards C++ where you can just run Shell commands. I also found something where you can use a FullTrustProcessLauncher but you have to modify the package manifest to get permission and, since this is a component, I can't do that.
