Count Number of Posts in Taxonomy Term in Last 24 Hours

Question

if anyone could help it would be greatly appreciated, been trying to get this done on and off for a long time and just can't get there.

I am using the function below in a loop to count posts within a taxonomy name. Function below works fine, but would it be possible to refine the function further to only count posts that were published within the last 24 hours? I found a similar questions but couldn't get it to work with get_term_by Count posts or custom post types from last 24 hours (or from today)

Any help greatly appreciated.

<?php
global $post;
$taxonomy = "news"; 
$term_name = $post->post_title;
$term = get_term_by('name', $term_name, $taxonomy);
echo $term->count ; 
?>

You can create a custom WP_Query and count its result.

$wp_query = new WP_Query([
    'tax_query' => [
        [
            'taxonomy' => 'news',
            'terms' => $term_name,
            'fields' => 'name'
        ]
    ],
    'date_query' => [
        [
            'after' => '24 hours ago'
        ]
    ]
]);
$number_of_posts = $wp_query->found_posts;

Edit

I removed posts_per_page argument, as @birgire suggests, that found_posts offers total number of posts regardless of pagination.
