https://glam.telemetry.mozilla.org doesn't hint that the use counters should be looked at in a totally different tool

[smaug----]

I was wondering about this probe https://glam.telemetry.mozilla.org/fog/probe/use_counter_deprecated_ops_doc_sync_xmlhttp_request_deprecated/explore? and couldn't see any data for it and thought use counters were broken, but apparently one needs to use totally different tool for them.
It is confusing that glam even finds the relevant probes when it can't show any data related to them.
