custom shortcode php. – include alt-text for images

Hello,

for my websites i have some pages that use custom shortcodes. For these shortcodes there are some .php-files in the wp-directory. I have access to these .php-files and can rewrite them.
The shortcodes i want to change are about implementing the featured image from some custom post types. When including the image, the alt-text of the image is not implemented, so the alt-text ends up missing on the live-page.
I already read, that this includes some code like “get_post_meta….”, but i am not that comfortable including code to a php. file.
Can anyone help me?

The original code for one of the shortcodes i want to change is

<?php
add_shortcode('clients_mixup', 'clients_mixup');

function clients_mixup($atts) {

    $terms = get_terms(array(
        'taxonomy' => 'clients_cat',
        'hide_empty' => true,
	'meta_key' => 'tax_position',
        'orderby' => 'tax_position',
    ));
    $count_terms = count($terms);

    $terms_id = array();
    $terms_names = array();

    ob_start();
    ?>
    <div class="custom-clients-container-btns">

        <div class="controls">
            <button type="button" class="control" data-filter="all"><?php _e("All", "bertschinnovation"); ?></button>
            <?php
            if ($count_terms > 0) {
                foreach ($terms as $key => $term) {
                    ?>
                    <button type="button" class="control" data-filter=".<?php echo $term->slug; ?>"><?php echo $term->name; ?> </button>

                    <?php
                }
            }
            ?>

        </div>

        <div class="clients-container custom-clients-container" data-ref="mixitup-container">
            

            <?php
