I definitely appreciate the helpfulness @Ptujec!

Thanks @lancethomps - working perfectly in my keyboard maestro macro on Sequoia 15.2

@lancethomps For some reason, your javascript code doesn't work for me on Macos Sequoia 15.2. The "result" tab in script editor keeps outputing "[object Object]" and if I run the script right after opening the notification center, then the script takes a bit longer to run and then an alert pops up saying "Error: Error: Invalid index."
