In VLC PLayer for Windows and Linux when playing a video file I can click a button or press CTRL + L to "hide" the video and view the playlist/library, handy for (pseudo) music videos.
In the view menu there is an option which shows the shortcut, this is not the case on macOS. Control and L do nothing, ⌘+L is for repeat all.

Is there a keyboard shortcut to do this on macOS?

On macOS VLC Version 3.0.11 (where the screenshot is taken from):
option + cmd + p => shows/hides playlist, it is in the Window menu - with the note that doesn't work in full screen.
