Display posts from specific slug of the custom taxonomy in Wordpress

Question

I have this piece of code, but what I really want to do is to get all post displayed from my taxonomy. Where do I place my taxonomy slug to make sure only a certain category posts are displayed? The category slug it's let's say "projects". How to filter this category? Currently it seems that it displays all my posts on the page. Here is the code:

  $myterms = get_terms('units', 'orderby=none&hide_empty');    
  echo  $myterms[0]->name;


  foreach ($myterms as $term) :

    $args = array(
        'tax_query' => array(
            array(
                $term->slug,
            )
        )
    );
    
    //  assigning variables to the loop
    global $wp_query;
    $wp_query = new WP_Query($args);
    
    // starting loop
    while ($wp_query->have_posts()) : $wp_query->the_post();
    
    the_title();

    
    endwhile;
    
    endforeach;

I would recommend becoming intimately familiar with the WP_Query parameters: https://developer.wordpress.org/reference/classes/wp_query/

In your particular case; dealing with taxonomies: https://developer.wordpress.org/reference/classes/wp_query/#taxonomy-parameters

Here is the proper code to pull from a taxonomy:

$args = array(
    'post_type' => 'post',
    'tax_query' => array(
        array(
            'taxonomy' => 'units',
            'field'    => 'slug',
            'terms'    => $term->slug
        ),
    ),
);
$query = new WP_Query( $args );

The taxonomy should be the slug of your registered taxonomy. In this case, I'm assuming units.
