Doesn’t work with WordPress version 6.3

Here is a GIF (https://share.getcloudapp.com/ApulByb0) of a fresh WordPress and we see a 404 response when trying to use the plugin.

It seems there are outdated comments here that were never answered, but this also seems to not work on multisite installations as well. Help! Would love to use the integration, but it doesn’t seem like its actually supported.
