How to enable menu bar icon?

[jju]

I have M1 macbook pro with Targus usb-c hub. I disabled the purple "your screen is being observed" icon because one of the streaming sites wouldn't show if I had that icon. When I tried to use DisplayLink again, it wouldn't show the menu bar icon and shows the message "DisplayLink Manager is already running. Menu bar icon is currently disabled..." I enabled every permission and setting that I can think of and reinstall, restart and everything but it's still not showing the menu bar icon.
