Azure WVD spring 2020 release announces many new capabilities and one of them is Azure Resource Manager (ARM) service support. Earlier, WVD was not native to ARM due to that there were lots of complexity to deploy it. If you have already deployed earlier WVD version then you have found that you have to give consent to AAD, use PowerShell to create WVD Tenant, use Web App for application management, and many more. Now it's all gone. You can simply go to the Azure portal to create a WVD environment using a new UI that is native to Azure.
