@pfefferle @mattwiebe Done. I hope in the future release it will implemented.
The only thing that concerns me is not installing the plug-in to my self-hosted WordPress due to this problem.

If in the future I have to move my host will it break my ActivityPub federation, comments on my blog, etc.

Since connection to ActivityPub is good and it will put a new breath to WordPress since the blog will be back as a blog since people can comment and discuss something not just a static site.
