### Problem Description
<!-- Is your feature request related to a problem? Please add a clear and concise description of what the problem is. -->
My electron version is 6.1.11, and I can't update because visibleOnFullScreen option on setVisibleOnAllWorkspaces is deprecated. It works fine on mac 10.15.4 and newer version.
To code like this:

  app.dock.hide()
  window.setAlwaysOnTop(true, 'floating')
  window.setVisibleOnAllWorkspaces(true, { visibleOnFullScreen: true })

The visibleOnFullScreen option is very important to my electron app and I'm so appreciate if you can check this feature again!
