Our team is planning to switch from Slack to Mattermost. We are currently testing some feature we using.
Now we have a self host mattermost running on ubuntu 22.04, and want to make it integrate with Trello.
We found this mattermost-app-trello from mattermost team.
But we got this message while trying to install it:
Command with a trigger of '/apps' not found.
According to this document, there is no “/apps” in build-in slash commands. So how do we make this work?
