Event Integration - Secureworks Taegis

I opened a support case and was directed to post here instead.

We are attempting to setup an event integration from Cato to Secureworks Taegis following this KB: Integrating Cato Events with AWS S3 – Cato Learning Center but when we get to the point of entering the bucket name, we are unable because Secureworks provides an S3 alias and not a bucket name. The Cato portal specifically prevents using an alias. How can we get this integration configured?
