How to check button press speed. any idea?

Hi how are you everyone?
Simple question:
is there a test somewhere online where i can check to see how fast im able to press a botton on my kb and no not the spacebar no not mouse clicks none of that. An actual let’s say key press of “A” or “1” or “Q” or “W”.
I found one last year but I since lost it and now can’t find it, maybe someone has an idea?
Thank you all!

Dont know if this will help, but I found this.

Thank you, let me try this
