Calls Plugin Producing Many Error Logs

Seeing millions errors about a non-existent “calls” plugin (com.mattermost.calls)

Steps to reproduce
Use 6.4.2 and view the logs (filtered to error entries).

Expected behavior
No errors.

Observed behavior
See lots of these errors:

    "timestamp": "2022-04-15 16:56:39.235 Z",
    "level": "error",
    "msg": "Access to route for non-existent plugin",
    "caller": "app/plugin_requests.go:37",
    "missing_plugin_id": "com.mattermost.calls",
    "url": "/plugins/com.mattermost.calls/channels",
    "error": "plugin not found: com.mattermost.calls"

I think I found the source of this error (a mattermost calls plugin on github), I have created an issue there as well.
