Office Store Add-ins and Centralized Deployment (oh my)

After diving into this further I'm 100% sure that turning off store access via the M365 Admin Center > Settings > Org settings > User owned apps and services (unchecking the blue box) does NOT prevent the use and centralized Deployment of Office Add-ins based on the article below.

"This does not prevent an administrator from using Centralized Deployment to assign an add-in from the Office Store."

When I tested this a few days ago though it disappeared from my Excel version, so the question is what are the required Office versions for both Windows and Mac to allow for Centralized Deployment to work?

My version (deployed successfully with access to store in place). Blue check box was checked.
