Make left-clicking the tray icon always "show" the program window?

Currently, at least on my installation of Linux Mint 20.3 XFCE, left-clicking the tray icon does the exact same thing as right clicking.

I would think that it would make more sense that left-clicking would simply always "show" the program window while right-click can be used for the pop-up context menu (other programs such as nheko behave in such a manner).
