Peertube Live Chat Plugin

Hello everyone,
after installing Peertube and uploaded all of my videos, i’m road to make my first live.
But for interact with my (small) community, i would like to use the LiveChat plugin.

Is it possible to install Prosody in the same container of Peertube ?
Or i need to install Prosody in another container ?
Or reinstall Peertube ?

Link of LiveChat plugin : peertube-plugin-livechat/installation.fr.md at main · JohnXLivingston/peertube-plugin-livechat · GitHub
Link of Prosody : Using Prosody with Docker – Prosody IM

Thanks for your further response
