This could simply be an improvement to documentation about how to configure Mattermost to use the NextCloud-hosted RTC server. If code changes are needed then this could be filed as an enhancement.
Basically this would tie together Mattermost as a chat app and NextCloud's video calling. A quick and easy way to support robust chatting without developing/securing in NextCloud.
Mattermost is a self-hosted FLOSS Slack-like app. It aims to support video calling via RTC servers.
