Ability to Enable Chrome Experimental Features: Web Share

**Is your feature request related to a problem? Please describe.**
`navigator.share() is not a supported function on Windows. Share API is not available in this browser on macOS.`

When using Standalone Chrome and enabling the Web Share as per the below:


It works as expected.

When disabling it in the browser, I receive `navigator.share() is not a supported function on Windows. Share API is not available in this browser on macOS.` as in the Electron app.

**Describe the solution you'd like**
In normal Electron, using `app.commandLine.appendSwitch('enable-features', 'WebShare');` should suffice to enable the Web-share functionality.

**Describe alternatives you've considered**
I have tried adding `app.commandLine.appendSwitch('enable-features', 'WebShare');` in different areas of the setup.ts to no avail. The Share API is still not available in the Electron app.

I have also tried adding `experimentalFeatures: true,` in the new BrowserWindow() function, but this has not changed the result.
