Open pop when the form is sent

Hello,

I need to display a pop up after the form is send. Is this possible?

I tried many ways using “on_sent_ok:” but doesn’t work.

Also I′m using the plugin “Popups – WordPress Popups” –> https://www.ads-software.com/support/plugin/popups/page/3

Someone can help me, please?

Thanks!!
