Certificate issue with 'Enter-AzVM' command in Cloud Shell

Question

I was not able to access my Windows Server VM from Cloud Shell, on account of a certificate error.
I'm following this documentation: https://learn.microsoft.com/en-us/azure/cloud-shell/quickstart-powershell#interactively-log-on-to-a-remote-vm

My instance is named 'mb2'. I was hoping to run:

Enable-AzVMPSRemoting -Name mb2 -ResourceGroupName mb2_group

cd 'Azure:/Free Trial/ResourceGroups/mb2_group/Microsoft.Compute/virtualMachines'

Get-Item mb2 | Enter-AzVM -Credential (Get-Credential)

But the final command fails:

PS Azure:\> Get-Item mb2 | Enter-AzVM -Credential (Get-Credential)

PowerShell credential request

It appears that the 'Enter-AzVM' command is failing on account of not knowing my VM's thumbprint.

I'm able to connect to the VM from my local machine using RDP (blindly accepting the reported thumbprint).

A chat session with Azure support was not able to resolve the issue.
