Countdown redirect with parameters?

Hello there,

I have a countdown timer on a sales page.
On timer expiration, I’ve set to redirect to another sales page.

I use URL parameters to personalize the pages with the leads’ first names.

I don’t seem to be able to set the redirect target url to include the url parameters the original url contains.

I’ve been able to redirect with parameters after a form submission, but after the countdown expiry it doesn’t seem to be possible…

URL example:
https://www.staging.professionacteur.com/la-formation-en-promo?prenom=TestName
needs to redirect to
https://www.staging.professionacteur.com/la-formation?prenom=TestName
when timer hits 0.

Anyway I can do this please?

Thanks for your help!
