Alexa Announcements

Hey there, first time posting, glad to be here.

I have been using SmartThings for some time now and looking to migrate all of it over to HA. In WebCore for SmartThings, I have some automations, which when triggered, can call an announcement routine in Alexa. For instance, I have my water leak sensors and a contact sensor on a fridge that when activated will call Alexa to "PlayAnnouncement ".

I’ve read through the HA Cloud integrations and multiple videos and they all are from the point of view of having Alexa reach into HA to perform some automations. I’m looking to go the other way - to have some automations call Alex and play an announcement.

As an example of simple WebCore code, I have it attached for the water sensor alert.

My question is - how do I do this in HA - more specifically, what type of integrations do I need to do? Do I still have to do the HA Cloud integration for Alexa or is there something else? Is there any documentation on what commands can be sent to Alexa?

Thanks!
