Conversation integration missing in Home Assistant 2021.5.5?

I recently installed Home Assistant 2021.5.5 on my Raspberry Pi 4 inside a Docker container.

I am trying to integrate Plex Assistant (GitHub - maykar/plex_assistant: ❱ Plex Assistant is a Home Assistant integration for casting Plex media to Google devices, Sonos devices, and Plex clients with Google Assistant, HA's conversation integration, and more.) and therefore need the Conversation integration but this does not show up for me when I try to add an integration. Neither can I see it installed on the Information page.

Is there something I am missing? How to I integrate the Conversation integration and enable it?

Following the documentation page

to the GitHub repo it appears to be part of HA core now.

I am relatively new to HA after being away for 2 years though.

This is what I see on the Information page:

Shouldn’t the integration appear here if it’s part of Home Assistant Core?

A very good question. It has a quality scale score of Internal which means it is part of core HA, I believe.

I got it working. I did everything from scratch and I may have missed a step before.
