So I have my laptop connected to a 24-inch monitor, which I use as my primary display. I use DisplayFusion's multi-monitor taskbar feature to manage and show the windows on my two different screens separately. I generally use my laptop's screen (secondary display) to play videos in full-screen while I'm working on some assignments on my main screen. My problem is that whenever I click on anything on my main display, DisplayFusion's taskbar on my second display pops up and makes the video player on my second screen not full-screen anymore. How do I change this behavior? I only want it to show up on pressing the 'windows' key when the mouse cursor is on my second monitor.

Here's a screen recording to make it clear. Notice how the taskbar pops up on the right screen when I click on the left screen
