Windows has issue with "windows" export in the multiWindow electron helpers

[mitchell-foote]

Describe the bug

All of the key combos rely on an export "windows" from the ./multiWindow.js electron helper file. For some reason, that export doesn't work when running on windows, and the key combos don't work.

To Reproduce

Steps to reproduce the behavior:

1. Go to any windows machine
2. Open a client
3. Try to make it a kiosk. It won't work.

Expected behavior

That kiosk + refresh will work.

Screenshots

If applicable, add screenshots to help explain your problem.

Additional context

I found a solve using the BrowserWindow api, allowing us to keep track of all open windows, and then filter down the ones that aren't the server.

We can then use that list for the key combos.

Pr coming shortly.
