Strange group in AWS Simple AD Directory named "GorillaBoyAdministrator"

I recently setup a Simple AD Directory using the AWS Directory Service. When I browse the Directory using Active Directory Users and Computers from a Windows 2016 instance, I noticed a group named "GorillaBoyAdministrator" under Users.

Googling this name does not produce any results. The group is configured as a "Security Group - Global" and has no members, however it is a member of Domain Admins. Does anyone have any idea what this group is for?

At this point, I am inclined to delete the directory and recreate it, although that would entail a lot of rework, since I have a bunch of dependencies already setup.

UPDATE: According to AWS Support, this group is created for WorkDocs, see answer below.

Spoke with AWS Customer Support and apparently this group is created for AWS WorkDocs. So it is an internal AWS group. The support agent seemed to indicate that it's safe to delete if there are no plans to use WorkDocs with the directory in question. To quote AWS support:

"So the group "GorillaBoyAdministrator" is created for WorkDocs service."
