RGPD notification

Hi support,
I imported some users to my new redone website.
These new users do not have the RGPD “checkbox” option checked because they were never checked.

Is there any possibility of showing some kind of message or popup to alert users that they need to check the RGPD “checkbox” after login?

And after they have checked the RGPD checbox, the message will never appear again.

Best Regards
