No L-G-T-M from a valid reviewer yet.
CQ run can only be started once the patch has received an L-G-T-M from a full
committer.
Even if an L-G-T-M may have been provided, it was from a non-committer,_not_ a
full super star committer.
Committers are members of the group "project-catapult-committers".
Note that this has nothing to do with OWNERS files.

hm, maybe it's not working because this is telemetry repo?
In that case I'd defer to achuith@ for putting this in.
