keyboard maestro

I am looking for someone to write a keyboard maestro macro on a Mac. You must have a mac to do this...not debugging non-Mac to Mac issues. I will provide step-by-step instructions, but in a nutshell, I want to be able to assign a hotkey (say F5 for now) that will grab the upcoming (in the next [configurable amount of minutes]) calendar invite, extract the Zoom link, and start Zoom. I will separately have logged into Zoom...so the automation doesn't need to do that.

Must use Keyboard Maestro. and hopefully nothing else is required to be installed on the machine (except the Mac calendar app, and Zoom)
