Popup window after submission via webform

Hello! Can you suggest a solution for this problem... There is a webform and a popups module. The form opens through a modal window from the popups, and after submission, it simply closes as expected. I need it so that after sending the message, a "modal window" appears with a message like "Message sent" or something similar))) How can I do this? ) I'm too lazy to dig into the module and add the popups class to the standard webform redirect. What options do I have? )
