Hello Troops
Thank you for reaching out to the Microsoft Q&A platform.
Azure Hybrid Benefit is a licensing benefit that lets you bring your on-premises core-based Windows Server and SQL Server licenses with active Software Assurance (or subscription) to Azure. If you have Windows Server licenses and SQL Server licenses on-prem, you can use them in Azure without paying extra for the virtual machines licensing costs.
You can verify the licensing type of your virtual machine by using the Azure portal, PowerShell, or Azure CLI. You can also monitor the assigned license utilization and assign more licenses if needed.
From portal VM blade, you can view the toggle for Azure Hybrid Benefit for Windows Server by selecting "Configuration" tab.
for details, you can see the following document https://learn.microsoft.com/en-us/azure/virtual-machines/windows/hybrid-use-benefit-licensing#how-to-verify-your-vm-is-utilizing-the-licensing-benefit
Please note that the usage above the number of assigned licenses will be billed at normal, pay-as-you-go price
