You published a RemoteApp named AppVersion1. Which PowerShell cmdlet will update the Remote Desktop client display name to Sales Contact Application?

The Update-AzWvdApplication cmdlet is used to modify properties of an existing Azure Virtual Desktop (AVD) application, including its display name. In this scenario, you are updating the display name of an already published RemoteApp, making this cmdlet the correct choice. New-AzADApplication is used to create a new Azure Active Directory application, which is not relevant to changing a RemoteApp's display name. Update-AzWvdApplicationGroup modifies properties of an application group, not an individual application. Register-AzWvdApplicationGroup registers an application group, which is a creation/registration operation, not an update of an existing application's display name.
