storage – Why the VHD file for OS Disk of a virtual machine is not in Azure Blob container

I tested with creating a resource group, a storage account (Standard and Premium in seperate tests) and a Ubuntu VM, and then used Microsoft Azure Storage Explorer to locate the VHD file.

From various articles, such as this ( https://docs.microsoft.com/en-us/azure/storage/blobs/storage-blob-pageblob-overview?tabs=dotnet ), the VHD file should be stored in a page blob container.

But in my case, there is nothing under ‘Blob Containers’ of my created Storage account.

The OS-Disk for the VM does appear under ‘Disks’, and then within the sub item sharing the same name as the VM.

I am wondering why this is the case. Why isn’t the VHD file in the Blob Container as is indicated by all articles that I have read so far.
