ashokjingar I just stumpled upon this thread and registered myself to tell you that theres a module that lets you fetch Office 365 groups that are used for abstracting a membership of af Teams team.

'MicrosoftTeams' |
ForEach-Object -Process {
    if (-not (Get-Module -name $_ -ListAvailable))
    {
        Install-Module -Name $_ -Scope CurrentUser
    }
    Import-Module -Name $_ -ErrorAction Stop
}

$connection = Get-Variable -Name connection -ValueOnly -ErrorAction SilentlyContinue
if (-not $connection)
{
    Write-Host -Object "There might be a MS login pop-up window that you havent noticed" -BackgroundColor Yellow -ForegroundColor Black
    $connection = Connect-MicrosoftTeams -ErrorAction Stop
}

#endregion Init

Write-Host -Object 'Fetching all Teams groups'
$team = Get-Team
Write-Host -Object 'Fetching all Teams groupmembers'
$teamUser = $team | Get-TeamUser

I doubt this because you actually aren’t adding any groups to teams!
you’re just doing a one time import of the member of those groups. So you’ll probably just see the members being added

  Thanks for your reply. If you read the following article, TonyRedmond makes a comment that in Azure AD, background synchronisation takes place eventually. Meaning that if you add a new user to a particular Group in Azure AD, that new user should eventually appear in the Team that uses that Group. So that would imply that Teams/Azure AD knows which Groups belong to which Team.

    Yes! There’s always a Office 365 group for every team! But you can’t add another group in the members section! Only add users or groups but it will then only import the users that are members of that group
    
    You should be able to get the underlaying office365 groups for the teams
