So I can access some of the properties of the endpoint, but appears only the properties listed here: 
The data I need is in extensionData which I don't seem to have access to still, or I simply don't know how to access it. I tried printing it out and also tried JSON.stringify(endpoint.extensionData));
Also I found using the input type of vCACCAFE:Endpoint as you mentioned below, then selecting the endpoint, I get the same results.
There is a chance this could work, if we can access and use the data in extensionData.
