SFSafariApplication.dispatchMessage for iOS Safari Web Extension?

Is it possible to send messages between the container app and the extension when working with an iOS Safari Web Extension? It seems to work ok on MacOS, but I can't find any documentation on how this would work on iOS.

Any help would be greatly appreciated.

This is explicitly not supported:

You can’t send messages from a containing iOS app to your web extension’s JavaScript scripts.
