how to execute a custom script based on a specific windows notification or edge notification (how to program the trigger?)

Question

I am looking for a way to run a custom script (which is located on my local drive) when I receive a specific notification (based on notification title?) or from an edge notification (from a specific url?)

I am using omnichannel on the CRM dynamics platform to receive phone calls in the edge browser, and now i want to make it more visible by using a USB led light, which I can manipulate using scripts that are stored locally on my computer. So for instance when a call comes in (it gives me an edge pop op and a windows notification and then it should run the script incoming_call, which makes the led blink red. The scripts work, but i have not found how to trigger it yet...
