Browse a CSV file with Powershell

Hello, I would like to read the contents line by line of a CSV fishie using PowerShell but I can't.
I tried this code but it doesn't show me the $Identifiant and $Nom values in ISE PowerShell console. :

$CSV = Import-CSV -Path "C:\Scripts\1234.csv" -Delimiter ";"

Foreach($Ligne in $CSV){
$Identifiant = $($Ligne."Identifiant technique du document")
$Nom = $($Ligne."Nom de fichier")


Write-host "Identifiant technique :" $Identifiant "Nom du fichier :" $Nom
}

I have this in output :

And my CSV file is like this :

Can you help me please ? 😞 Thanks in advance !
