You must be logged in to post a review not translating (WPML)

Hello,
in the reviews form (shortcode) the text “You must be logged in to post a review” is always shown in English (default language).
Using the filter ‘comment_form_defaults’ we can print the form fields and we can see some texts for the comments.
How can we translate or change this ‘You must be logged in to post a review’ text?
Thanks for your support,
Carles
