How to display some text when a review is successfully submitted

Hello,

I would like to approve the reviews once they are submitted.

At the same time, I would like to tell the user that his review has been submitted correctly and it is under review (and that’s why he does not see it on the website).

How can I display some text, maybe a pop-up, just after the submit of the review? Is it possible to do?

Actually my page refresh after submission (I set it thanks to your suggestion), but maybe is better some text to acknowledge the correct submission.

Thanks a lot,
Daniele
