How to Display the Page Title inside an overlay section (inside single post Layout)

Hello,
I have the Blog app installed on my website.
On each blog page, I present a specific service.

At the end of the page, I have a contact button that opens an overlay section, with a form.
I’d like this overlay section, when opened, to display the page title at the top.

I managed to do this on another site using the Zero app:
– I added a hidden field to the form I created, and then, in the lightbox, I added a FIELD plugin with the page title.

However, in the Blog app, the FIELD plugin isn’t available.

Is there any alternative way to display the Page Title in the overlay section?

Maybe I wasn’t very clear in my explanation.

Thank you,
