[SOLVED] Undocumented Wunderlist delete task-comment endpoint

There appears to be an endpoint on the Wunderlist API for deleting a task-comment which does not appear in the official docs

Existing task comments can be deleted by sending a DELETE request to it, e.g. :

curl \
    -H "X-Access-Token: $WL_ACCESS_TOKEN" \
    -H "X-Client-ID: $WL_CLIENT_ID" \
    -XDELETE \
    https://a.wunderlist.com/api/v1/task_comments/12345?revision=1

Assuming the data is valid, this returns with HTTP 204.

Is this endpoint supported?
