How to count post based on taxonomy term in WordPress?

Question

I have 2 custom post type which is

a) support
b) item

and custom taxonomy called item_category

I have set this taxonomy to those 2 custom post.

Now, I want to count the post from support custom post based on added taxonomy term.

For example:

Taxonomy item_category has 3 terms : 1) blog 2) lms 3) event

I have added this term blog to support custom post.

Now, I want to get number of post from only support post type under blog term

To do that I am using

$item_categories = get_terms(array(
    'taxonomy'   => 'item_category',
    'hide_empty' => false,
));

echo "<ul class='card-content'>";
foreach ($item_categories as $item_category) {

    echo '<pre>';
        print_r($item_category);
    echo '</pre>';

    $item_category_id   = $item_category->term_id;
    $item_category_name = $item_category->name;
    $item_category_slug = $item_category->slug;
    $item_category_count = $item_category->count;

    echo "<li><a href=".site_url("/support/?item_category={$item_category_slug}").">";
        echo "<span class='lnr lnr-chevron-right'></span>{$item_category_name}";
        echo "<span class='item-count'>{$item_category_count}</span>";
    echo "</a></li>";
}
echo "</ul>";

But its counting from both support and item custom post. I want only from support post.

Currently, the output is like that with count value but the count is wrong according to my need.

is it possible?

You can get posts related to taxonomy with a tax query:

$posts_array = get_posts(
    array(
        'posts_per_page' => -1,
        'post_type' => 'support',
        'tax_query' => array(
            array(
                'taxonomy' => 'item_category',
                'field'    => 'term_id',
                'terms'    => $item_category_id,
            )
        )
    )
);

echo count($posts_array);
