How does Hubitat support Ecobee switch+?

This is really a question to the HE team but maybe someone else knows... How does HE manage to integration Ecobee switches into the Integration? Are you part of the partner program or something? When I make the API calls to get the LIGHT_SWITCH devices I get authorization errors which I suspect means the API Key I have doesn't generate an OAuth token with the scope needed. How did Hubitat manage to get this working? Looking on the Ecobee website I don't see you guys listed as a partner so figured I'd ask! Ecobee is silent on how to get this data via their API. After initially being told I could do it by their tier 1 support, I eventually was told "it's impossible." When I asked how SmartThings and Hubitat did it they told me they didn't know.
