Can i create custom overlay populated by query loop data?

Hello GP Team!

Im trying to create a universal popup for all experts on the site, where someone can send a message (email) either directly from the Experts page (archive page of CPT), or directly from a profile page.

Currently on the experts page, every query loop has a “Send Message” button > and i want this to open an overlay panel.

The overlay panel would have
-Expert featured image
-Name
-Expertise
(all existing fields within the CPT, some are custom ACF fields)

Followed by a form that has a couple simple fields:
-Your message
-Your name
-Your email
(but also has a hidden field(s) that includes the expert info like name and email)

Is this possible with generatepress?

I tried building it but the dynamic stuff is currently just referencing the “Experts” page itself, and not the expert I clicked.

Any help is much appreciated
