Change origin server details in Essential App Protect

Hello DevCentral team.

I have just signed up for a free 15 day trial of Essential App Protect online.

I updated the CNAME in my dns settings and my website is working right now via the previous CDN i was using.

I would like to get the EAP to point to my origin server directly and bypass the previous CDN.

How can i update this in the EAP in the management portal?

Regards
