Resume from Suspend

I have a question about waking my system up after suspend.

I have suspend/resume working fine but I only can wake it
up by pushing the power button. This works perfectly fine.

Is there any way to wake the system up from a usb keyboard.
Means pushing a button on the keyboard instead of using the
power button for wake up?

The computer is a Dell Optiplex 7060 (2018) with Intel graphics.

I searched the net for an answer but only came across general
suspend/resume issues, but nothing about the fine tuning.

Does someone can point me in the right direction?

Think about it. When the system is suspended nothing is running, how is the OS supposed to handle this situation if there's no (OS) code running on the CPU? Waking up the system from a keyboard press is a hardware feature. The hardware has to wake up first, then some code from the OS can start running on the CPU again.
