What is the adapter Certificate for CTA

[taasai]

Hi,

I'm working on the configuration of TC-NAC on ISE 2.4 for CTA. In the admin guide, it says you need to import the certificate into the trust store on ISE.

Where can I get the certificate and what is it? Is it the certificate you can copy when you access to the cognitive.cisco.com by the web browser like the following?
