Controlling presenter minimized

We are using a two display set up. The one is where the computer software is operating (zoom, audio mixing software, logos Bible software) and the other is for lyrics on screen during worship. We noticed that if we minimized Presenter we can no longer use the keyboard to advance slides. Could this be done if using the remote or midi, or would the application need to be visible on the main screen to control it either way?

The Remote app works just fine when minimized. MIDI inputs should work too but I'm not sure about that one, I don't use it.

If you are using Windows, it may be that minimising the Presenter screen takes the focus away from it. So, when you use the keyboard commands, they are not directed towards Presenter.
