Could not publish LiveUpdate content to AWS

Thanks, have successfully uploaded resources to AWS S3.
But I have question, I have found here Defold 1.2.97 has been released that:

Addressing a collectionproxy with collectionproxy.missing_resources can only be done from a script that is in the same collection as the target collectionproxy. A workaround is to use messaging instead.

Can you please tell if it is already possible to manage now?
