Full screen gallery does not work

Excuse me for my basic English.
I have a website where the galleries of my works are in full screen and I like that a lot.
Now I'm trying to move my website to the WordPress design with Elementor Pro and generate a premium press, but the same code does not work for my photo gallery anymore. (I'm not an expert in codes)
The problem is when the generation of the press is active. If I deactivate it, it works correctly.

Here you can see how the galleries work correctly on my old website:

And this is the new site: (where it does not work with Generate Press activated)

It does not work full screen and does nothing.
I would appreciate any help. Thanks for your kindness.
