Hi, Jan, does that merged PR fix this?

I believe not. This PR is about adding typescript types to the extension code instead of using any/object types. It wouldn't change any interfaces. In my opinion, this is a lower-priority internal cleanup.

Hi @IanWyszynski, is this a fix that you'd like to take on, or should we assign it to another maintainer to take a look?
