Add product tags or terms programmatically in WooCommerce but keep the existing ones

I've been reading about this functionality that I'd like to implement on my WooCommerce. The idea is that once a product is sold out, a new category "Sold Out" is automatically assigned to it.

Luckily, I've come across this answer code. I added this piece of code:

function action_woocommerce_no_stock( $wc_get_product ) {
    $term_ids = array(769);
    $tag_ids = array(770);

    // Set category ids
    $wc_get_product->set_category_ids( $term_ids );

    // Product set tag ids
    $wc_get_product->set_tag_ids( $tag_ids );

    // Save
    $wc_get_product->save();
}
add_action( 'woocommerce_no_stock', 'action_woocommerce_no_stock', 10, 1 );

To my functions.php and it works! the problem is that it overwrites all previous categories.

If anyone can guide me how to obtain the previous "product_cat" array and add them with the "Sold Out" category (769) I'd greatly appreciate it.

You can first use get_category_ids() OR get_tag_ids() and then array_merge()

So you get:

// Get product via product ID
$product = wc_get_product( 30 );

// Add this new term IDs
$term_ids = array( 15, 30 );

// Get existing category IDs
$category_ids = $product->get_category_ids();   

// Set category IDs
$product->set_category_ids( array_merge( $term_ids, $category_ids ) );

// Save
$product->save();

Note: in your case $wc_get_product is equal to $product
