Cannot delete AWS Lambda@Edge replicas

I found part of an answer:

It turns out that I needed to delete the trigger in the behavior of Cloudfront.
Simply:

• Go to your Cloudfront distribution's behaviors
• Check the one triggering the LambdaEdge
• Click Edit
• Go at the very bottom of the page and click the X to delete the trigger

Still, I can't delete the replicas but at least I can create new lambdas for this trigger...

I asked this problem to AWS support and its answer was like: "you cannot delete replicated lambda functions for now, but we understand many people requires this".

AWS Lambda@Edge http://docs.aws.amazon.com/es_es/lambda/latest/dg/lambda-edge.html

When you create a trigger, Lambda replicates the function to AWS Regions and CloudFront edge locations around the globe. Note that replicas can't be edited or deleted.

There is now a documentation here stating that replicas are deleted after a "few hours" - which would imply that I then can also delete the Lambda function.

Update 2020-01-05: If you delete the Lambdas it takes ~1 h and everything is gone! So it is just slower but behave similar to normal Lambdas?
