How to send clicks to an inactive window?

Question

Windows

There is a python bot that starts the game and emulates keyboard keystrokes via autopy, but the keystrokes are sent to the active window. At the same time, I want to do my own business on the computer. How can I separate computer control so that my activity and bot clicks can coexist? I do not like the option with a virtual machine, the performance inside it is not enough.
PostMessage didn't work with this game
