How can I invert the color of a selected/using window in Window 10

Question

I want to invert a pdf window (Mendeley Viewer) for dark mode reading. The current color filter or magnifier in the setting will invert the whole screen. Are there any application or method that I can use to invert only a selected/using window instead of the whole screen?

In Ubuntu, I can easily do this by super + I. It will be strange if Window doesn't support something like this.

You can use the program https://windowtop.info. Its free version allows users to invert only a selected/using window instead of the whole screen
