1 - No message if no user or no group have been selected :
To reproduce :
1a - Fill only a message (set user list and group list empty)
2b - Click on Send button => Pop-up is closed KO
=> A message should be displayed (telling that no user nor group have been selected) and pop-up should not been closed.
2 - Message is a mandatory field, consequently "Vous pouvez ajouter un message ..." is incorrect.
It should be : "Ajoutez un message personnalisé de 200 caractères maximum"
=> To be done also in english : "Add a personalized message of 200 maximum characters"
3 - Tool tip is not homogeneous (de la page, des pages) :
Update the first part "Ce bouton ... de la publication des pages".
=> In english :
Update the first part : "This button ... that the pages are published online."
