Powershell - Search Azure/Entra AD for current status of an employeeID accounts using Graph Batch

Graph is a pain to work with if you are like me and just a scripter 

Takes a list of employee IDs via the $employeeIDs variable 
Queries Azure AD via Microsoft Graph in batches of 20
Retrieves userPrincipalName, employeeId, accountEnabled, 
and LastPasswordChangeDateTime
Outputs results to console and CSV

Connect-MgGraph -Scopes "User.Read.All"

$employeeIds = @"
EMPID
0000001
"@ | ConvertFrom-Csv

$employeeIds = $employeeIds.empid   

# Create batch request body
$batchRequests = @()
$batchSize = 20  # Microsoft Graph allows up to 20 requests per batch
$idCounter = 1

for ($i = 0; $i -lt $employeeIds.Count; $i++) {
    $request = @{
        "id" = "$idCounter"
        "method" = "GET"
        "url" = "/users?`$filter=employeeId eq '$($employeeIds[$i])'&`$select=userPrincipalName,employeeId,accountEnabled,LastPasswordChangeDateTime"
    }
    $batchRequests += $request
    $idCounter++
}

# Split into batches of 20 which i believe is the limit 
$batchedResults = @()
for ($i = 0; $i -lt $batchRequests.Count; $i += $batchSize) {
    $batchEnd = [Math]::Min($i + $batchSize, $batchRequests.Count)
    $currentBatch = $batchRequests[$i..($batchEnd-1)]
    
    $batchBody = @{
        "requests" = $currentBatch
    } | ConvertTo-Json -Depth 10

    # Send batch request
    $response = Invoke-MgGraphRequest -Method POST -Uri "https://graph.microsoft.com/v1.0/`$batch" -Body $batchBody
