Dynamic Shortcode or Iframe

I’m creating a site for a non-profit. They hold events and occasionally need to have a head count to know how many people to expect. I’m using Jet Elements to create my custom fields and Meta Data. I am creating a single page for each event with Elementor Pro.
For the RSVP form, I connected Caldera Forms with a google sheet connector and it works beautifully. The Caldera form has a shortcode. When I try and enter it into the events page dynamically it won’t work. When I just enter it in it does work.
I also thought about just embedding a Google form on the page, but the dynamic iframe doesn’t display either.
ANY HELP WOULD BE APPRECIATED! I’ve spent hours on this.
(I did look into zapier webhooks as well, but it would cost the non-profit $120 a year and they only hold events a few times a year… seems like a lot of money for somehting they won’t use a lot. I also looked into RSVP plugins which only do one event or are too expensive or no shortcodes.)
