How to do a global search on the screen?

Question

Python

Have a nice weekend and an easy week at work.
Let me know if someone knows.
It is necessary to write a program that will globally monitor the screen and if the necessary element is found, for example, an image (red circle), it will click on it.
At least in which direction to dig?
Thank you.
