Help Needed: Resetting Entra User Passwords with a CSV Script

Hey everyone, I'm trying to reset some user passwords in Entra using PowerShell, and I'm having a bit of trouble. I've got a CSV with Entra ID users and my script is supposed to import the CSV, go through each user, and reset their passwords. But when I run the script, it doesn't seem to be working correctly. I'm just testing it with one user (myself), and I'm not prompted to change my password when I log in next. Just to clarify, we're working in a cloud-only setup, so all users are through Entra, and there's no AD domain involved. Any ideas on what might be going wrong here? Here's a snippet of my script:

```powershell
# Define path to CSV
$csvFilePath = "C:Userspwd-rst.csv"

# Load CSV data into variable
$csvData = Import-Csv -Path $csvFilePath

# Define force password change after sign-in
$ForceChangePasswordNextSignIn = "True"

# Loop through users in CSV and update their password
foreach ($row in $csvData) {
$userPrincipalName = $user.UserPrincipalName
$userPassword = $user.Password

# Check if user exists
$existingUser = Get-MgUser -UserId $userPrincipalName -ErrorAction SilentlyContinue

if ($null -ne $existingUser) {
try {
$params = @{
PasswordProfile = @{
password = $userPassword
ForceChangePasswordNextSignIn = $ForceChangePasswordNextSignIn
}
}
Update-MgUser -UserId $UserPrincipalName -BodyParameter $params -ErrorAction Stop
Write-Host "Password updated for user: $userPrincipalName" -ForegroundColor Green
}
catch {
Write-Host "Failed to update password for user: $userPrincipalName" $_.Exception.Message -ForegroundColor Red
}
}
else {
Write-Host "User not found: $userPrincipalName" -ForegroundColor Yellow
}
}
```

Any insights would be greatly appreciated!
