Window's Snap Assist does not find my electron application

Question

I am trying to figure out how to get Windows to Snap Assist my electron window (display thumbnails of open windows after snapping another window to one side).

For some reason, when I snap another program to half the screen, when it gives the option to select an app for the other half of the screen, my app is not available in the options.

Is there a feature or BrowserWindow configuration that needs to be turned on/set for this to work?

EDIT: I wanted to note that I know this can work, as it works in other apps like Slack and Discord.

EDIT: Adding the settings for my main browser window:

mainWindow = new BrowserWindow({
    title: app.getName(),
    width: wndSettings.size.width,
    height: wndSettings.size.height,
    resizable: wndSettings.resizable,
    frame: false,
    icon: windowIcon,
    alwaysOnTop: false,
    show: false,
    autoHideMenuBar: true
});

mainWindow.on('ready-to-show', function () {
    mainWindow.show();
});

Resizable is initially set to false during a login screen, but becomes true once logged in.

I know that this thread is fairly old. Although, had the same issue just recently. For me removing transparent : true when creating the BrowserWindow object fixed it.
