PnP PowerShell
CLI for Microsoft 365


function CreateLibraryWithCT {
    param ([string] $LibraryName)

    $ctName = "My Custom CT"
    $libExist = Get-PnPList $LibraryName -ErrorAction SilentlyContinue
    if ($libExist) {
        Write-Host "Library - $LibraryName already exists" -ForegroundColor Yellow
    }
    else {
        #Creating library with Document library template
        New-PnPList -Title $LibraryName -Template DocumentLibrary
        Write-Host "Created Library: " $LibraryName -ForegroundColor Green
