Hi, I am a web dev who has only briefly tinkered with the D2 API and I had a quick question I didn't want to post in the Issues on Github, as it's not really an issue / defect; more of something I've tried googling to no success. Basically: I'd like to create a few challenges for raid groups to complete where they'd be in orbit, start the challenge on the site I'd build, which would query the API to grab details on everyone in orbit and effectively log all equipment in use at that moment and then fail the challenge if it detects something changed (like a poor-mans equipment lock). I know I can grab equipment information on people in the fire team, but is there a way to subscribe / listen in for changes to equipment so I can auto-fail the challenge without periodically pinging the API to get the live equipment list and compare to the "logged list" I took at the start?
