Trouble using the “Popups for Divi” extension with “Divi Form”

Hi everyone!

All plugins, Divi and WordPress are updated.

I have a problem using the Divi Form Module with Popups for Divi.
I thought that it was easy to create what I had in mind, but apparently not for some reason.

I’m trying to show a pop-up while a mail has successfully been sent via the Divi Form. In this pop up, I just want to put a lottie file with an animation, like “oh great, your mail has been sent!”.
I uploaded the popup for divi plug in, everything’s fine, but it doesn’t work.
Do you have any idea, solution, or is it impossible to do? ??

I’ve created a section with my Lottie animation and set it up as a Popup with the extension.
Then, I created the ID mail-successful, and as a Redirection Link in the form, I’ve put the #mail-successful anchor.
The website is under construction but I let this page open for you to check! -> https://mindblow.fr/devis/

You can see the Popup while clicking on the test button just beside the form

Thank you in advance for your help!

Best regards,
Matthias
