Hey David, thanks for reply. It almost works.
I put my code into Elements area, and here is a fun part. When I remove last product from the cart – when I am at cart page, it just leaves it blank, but if I do reload (F5), it loads what I wanted to put there just fine…
Okay, I figured that this snippet is not required, but, if I don’t reload, it actually ignores CSS from Elementor (I made a template in it, and put shortcode to it in this element)
