try{

    $url = "http://abc.sharepoint.com/sites/"
    $owner = "Terry"
    $displayName = "TerryTeam"

    $group = New-Team -DisplayName $displayName -Description $description -Visibility Private -Owner $owner 
        
    Add-TeamUser -GroupId $group.GroupId -User $user 
    Add-TeamUser -GroupId $group.GroupId -User $user -Role $owner

    $siteUrl = $url + $group.MailNickName

    # ---------------Get result---------------

    $teamName = Get-Team -GroupId $group.GroupId | Select-Object DisplayName # 1
        # or
    $teamName = Get-Team -GroupId $group.GroupId # 2
    $teamName.DisplayName
        # expect = TerryTeam
        # result = wondering this code can really work or not.
        # Q1 = Want to know 1 or 2 which can really work? Or both can't?

    $teamOwner = Get-TeamUser -GroupId $group.GroupId -Role Owner
        # expect = Terry
        # result = Microsoft.Teams.PowerShell.TeamsCmdlets.GetTeamUserResponse
        # Q2 = I think the code is no porblem, but keep error like this.
    $storageResult = Get-SPOSite -Identity $siteUrl | Select StorageQuota
        # expect = 10240
        # result = @{StorageQuota=10240}
        # Q3 = Did I missed some solution?
