How to add Nextcloud Assistant to the Talk app

According to Meet the Nextcloud AI Assistant - Nextcloud, published October 11, 2023, " In the following weeks, [Nextcloud] we are bringing the Nextcloud Assistant to Talk.". So its been several months, I assume this feature has been added, but I can’t find it. I’m curious how I enable or use this feature in the Talk app. While I’m talking about this, I saw in a video, https://youtu.be/_T5cqNWkky0?t=240, there is AI inline the text editor. However, this doesn’t work either. I would love to know how to enable these features, thanks Nextcloud team.
