You will have to generate a Peertube image that includes Prosody in the same container that Peertube.I know this is not the standard way to do this with Docker, but keep in mind it is a temporary workaround.
But it may be removed in a near feature (to avoid drawbacks of this method).I have to discuss with Yunohost team, to decide how we can do to minimize drawbacks, and maximize compatibility.
Before updating to a major release, please read the release notes and breaking changes list : [CHANGELOG](https://github.com/JohnXLivingston/peertube-plugin-livechat/blob/main/CHANGELOG.md).
If you have just installed/upgraded the plugin, but nothing happens (no chat, no settings, buttons in the settings page does not work, ...), just try to reload the page.
