Filter posts from category with ajax?

Question

WordPress

Hello!
I have posts from all categories displayed on the main page, I want them to be filtered only by the selected category on Ajax when you click on the filter on top.

I found an article on how to do this, only there for my taxonomies. Here , and I have a normal post type.
I can make mistakes and write incorrectly, I don’t understand well
. Please tell me how to do this. Thank you very much in advance.

$args = array(
    'post_type' => 'post',
    'category_name' => $category,  // https://wp-kama.ru/function/wp_query#parametry-kategorij-rubrik
