Can I trigger AWS SNS from Netlify Function?

My understanding from a while ago was that Netlify (Serverless and Background) were facades over AWS Lambdas. Is it possible to use a Netlify Function as an event source for AWS SNS or EventBridge?

From my limited understanding of Event Sources, I believe all those AWS services need to be in the same AWS account? If that’s true, I don’t think it would be possible using Netlify Functions as they’re deployed to our AWS accounts and any other AWS service you’d use would be in your account.

On the Enterprise plan, we allow users to deploy Netlify Functions to their own AWS accounts, so maybe it’s a possibility there.
