Can i use Window App SDK + Entra ID for Push Notification for MSIX app + submit to MS Store

I'm planning to use Flutter to build a Windows app, using an MSIX installer.

I need to distribute my app via

• MS Store
• Sideloading MSIX with manual certificate signing.

Features my app needs

• Push notification

My Question:

• Can i use Entra ID + Window App SDK to implement the Push notification feature and it will work on both MS Store app + Sideloading app?
• Because from this article: https://learn.microsoft.com/en-us/windows/apps/develop/notifications/push-notifications/push-quickstart
• -> It said that "We do NOT support using Windows App SDK push notifications with Microsoft Partner Center.". But i don't really understand what does "Not support" means. -> Does it means that if i implement the Push notification using Entra ID + Windows App SDK and upload to MS Store -> The push notification will not work? Or MS Store will reject my app?
