Mmomni: command not found

I’m running the Mattermost Omnibus on a Ubuntu 22.04 instance. Everything is working fine so far. However, I’m trying to enable the plugin upload feature.

I’ve updated the /etc/mattermost/mmomni.yml file appropriately, but when I try to run the command mmomni reconfigure, I get the following result: mmomni: command not found. I’ve checked and that command doesn’t exist in the bin folder.

What am I missing? Do I need to install it somehow? Any help on this would be greatly appreciated. Thanks.
