I cannot tell you how to apply this to a page template created in elementor theme builder, that would be a questions specific to elementor.
All I can tell you is how you would do this using PHP code
$current_page = get_query_var('paged', 1);
if ($current_page == 1){
// content only on first page
}
I did find this, don’t know if it will be helpful or not: https://stackoverflow.com/questions/69097872/how-to-assign-elementor-template-to-only-first-page-of-archive-category
