Enterprise Mode Cloud Site List policy help (InternetExplorerIntegrationCloudSiteList)

Good evening! This week I've been focused on configuring and evaluating the IE mode policies currently available for Edge. We plan to start our testing with an Enterprise Mode Site List and I initially planned to use the InternetExplorerIntegrationSiteList policy and place the XML export in the same on-prem location as our IE site list.

I was configuring the policy in Intune and I stumbled across the InternetExplorerIntegrationCloudSiteList policy. This policy states:  

The Microsoft Edge Site Lists setting in the M365 Admin Center allows you to host your site list(s) in a compliant cloud location and manage the contents of your site list(s) through the built-in experience. This setting allows you to specify which site list within the M365 Admin Center to deploy to your users.

... If you configure this policy, Microsoft Edge will use the specified site list. When enabled, you can enter the identifier of the site list that you created and published to the cloud in M365 Admin Center.

So far, I've failed to locate anything in the M365 admin center related to site lists. I noticed this policy was added for Edge 93, so I'm starting to think it simply isn't ready for prime time use yet. If anyone has any additional information or can link me to another discussion on this topic, that would be greatly appreciated!
