Observed behavior
Hello,

I use mattermost 7.7.0 team edition deployed via the chart helm mattermost-helm/charts/mattermost-team-edition at master · mattermost/mattermost-helm · GitHub

When I want to activate plugins I saw that pluging pre included (like playbooks) are not available after the activation. I checked the logs and there are logs after my activation.

I tried to create a folder in the /mattermost/plugins folder from the pod’s terminal and got the same error : permission denied. How can I fix that ? I can’t run chmod from the terminal. If I type whoami from the pod’s terminal it writes 1001060000.
