Sorry I will not, this is a learning opportunity to learn how to write a notification. And one you’re going to need.
Also - don’t try to slam something you’ve never done into an existing complex automation.
Instead start small. Make a single notification automation that you can call to say something simple to last Alexa. When you know that works. THEN try to integrate.
Why - last Alexa is flaky enough (if you overrun your calls in a certain time Amazon will throttle the api - blocking announcements) and many other things will go wrong. - you need to figure out if it’s your call to Amazon or your other automation. By having a standalone simple automation you can test. It simplifies troubleshooting.
