Hello,

Try to add the following PHP code snippet to the child theme in the functions.php file.

add_action('woocommerce_after_shop_loop_item', 'add_a_custom_button', 5 );
function add_a_custom_button() {
    global $product;

        if( $product->is_type('variable') || $product->is_type('grouped') ) return;

       echo '<div style="margin-bottom:10px;">
        <a class="button custom-button" href="' . esc_attr( $product->get_permalink() ) . '">' . __('View More') . '</a>
    </div>';
}

Best Regards.
