When browser is in French language, requesting a code doesn't work.

Describe the bug
When browser is in French language, requesting a code doesn't work.
I test it also with English, German and Italian, works well.

To Reproduce
Steps to reproduce the behaviour :

Requirements :

• First, request a signature with email address.
• Set your browser language in French

Step :

• I'm not an authenticated user
• Click on the button of the email received to sign a document
• Click on "Définissez votre signature."
• Draw signature
• Click on "Sauvegarder"
• Click on "Sauvegarder"
• Click on "Signer le document"
• Enter the email
• Click on "Demander un code".

The notification displayed is : "La requête de signature du fichier à été correctement soumise."
Which mean "The file signature request has been correctly submitted."

No code is received by email.

Expected behavior
The message of the notification should be "The code to sign file was successfully requested." in french "Le code pour signer le fichier a été demandé avec succès."
