Device Inventory > Inventories > Application not showing

shahulsk There can be a number of reasons why this is happening. I would start with verifying the licensing for the user. I think that user would need Windows Enterprise E3 licenses with MDE Plan 1. 

Then I would make sure the application is properly installed with the right registry key. Doing a quick search in the docs it shows this key: 

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender

This is the reference in docs: Troubleshoot Microsoft Defender for Endpoint onboarding issues | Microsoft Learn

Hope this helps.
