How to set custom zoom scale for lightbox?

Since there doesn’t appear to be any option to choose how much the image is zoomed when in the elementor lightbox mode and double clicked, or if the magnify button is clicked, I went into the inspector mode of my browser to see what’s going on.

I found the location in the code where I can alter the value from 3 to something else, but since I am woefully incapable of writing custom CSS, I am at a total loss as to how I can force the elementor lightbox zoom to be set at something other than a scale value of 3. 3x zoom is way too much. I would want something more around 1.5-2 for a scale value.

In terms of scale, I can change it manually on the live site with the inspector tool here:

transform: translate3d(0px, 0px, 0px) scale(3);

Is this enough to write custom CSS to force all of my image lightboxes to scale to something other than 3 on the whole site? Or at least the whole page?

Thanks for any help anyone can provide. Hopefully it’s simple and I am just too ignorant about this subject to get it. haha
