Documentation details required

Hi,

The documentation page for Phish Threat Configuration requires to be updated with few more details.

https://doc.sophos.com/central/customer/help/en-us/ManageYourProducts/PhishThreat/index.html

In this page step.2 talks about "Verify your domains", but we need to mention that it will require "Super Admin" user to verify domain. Mostly customers are trying it with admin user and getting error "max of 1000 reached" and a pop-up "get domain list failed"
