What are the URLs our IT department needs to whitelist to ensure your app works on student devices?

We currently have a cname entry for a new cloudfront cdn ( s.easycbm.com and static.easycbm.com) that is active but not put into the code yet.

When there are teachers involved, then we have to add the recaptcha servers which are many… which we don't have a list of all of them.
