Unable to connect to Teams with Powershell Module V2.0.0 in docker

Question

I can connect to Teams with the Powershell V2.0.0 module installed using snapd on Ubuntu v19.10 and Ubuntu 20.04.2 LTS:

I can install the MicrosoftTeams module using the official powershell image on Docker, but when I try to do Get-CsOnlineUser, I get an error:

Docker file:

from mcr.microsoft.com/powershell

RUN /opt/microsoft/powershell/7/pwsh -command "Set-PSRepository -InstallationPolicy Trusted -Name PSGallery"

RUN /opt/microsoft/powershell/7/pwsh -command "Install-Module -Name MicrosoftTeams -AllowPrerelease -Force -AllowClobber"

Script to execute:

$teams_username = 'XXXXXXXXX.onmicrosoft.com'

$pword = ConvertTo-SecureString -String 'XXXXXXXXX' -AsPlainText -Force

$credential = New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList $teams_username, $pword

I found this article very useful:

The final solutio was to install WSMan on my docker image
