How do I have my form pop up on my Wordpress site opening, and how do I delay that by a five seconds?

I have my Jotform (email sign-up) attached to my Wordpress page, but now I want it to pop up, with that five second delay. Are there instructions for this? Thanks...

My understanding is that you want a Lightbox form to appear with a 5 seconds delay. If yes, then please refer to these guides:

How-to-Create-a-Lightbox-Form
How-to-Auto-popup-a-Lightbox-Form

Hope that helps. Thank you.
