Setup localisation with the bricks/builder/i18n filter

Hi there,
is there anyone familiar with how to setup internationalization with bricks for the builder?
I tried useing the bricks/builder/i18n filter but I can’t get it to work.

If I use it like this, the default bricks translations are lost, but without the load_child_theme_textdomain function it won’t work at all.

add_action('after_setup_theme', function () {
    load_child_theme_textdomain('bricks', PATH_THEME . '/lang');
}, 11);

add_filter('bricks/builder/i18n', function ($i18n) {
    $i18n['ufContentFlow'] = esc_html__('Content-Flow', 'bricks');
    $i18n['ufDisableContentFlow'] = esc_html__('Disable Content-Flow', 'bricks');
    $i18n['ufFlowExplanation'] = esc_html__('Add space between content items,for a flowing layout', 'bricks');
    return $i18n;
}, 1);

How do I need to setup my Text Domain and Domain Path in the style.css?
This what it looks like at the moment, but I also trief a custom name for the Text-Domain

/*
 Theme Name:   userfreunde Theme
 Theme URI:    https://userfreunde.de/
 Description:  Custom userfreunde child theme to extend Bricks.
 Author:       userfreunde GmbH
 Theme URI:    https://userfreunde.de/
 GitLab Theme URI: ***********
 Template:     bricks
 Version:      0.1.2
 Text Domain:  bricks
 Domain Path: /lang
*/

I have a folder in my root theme folder lang, where the necessary translations are stored as e.g. de_DE.mo,de_DE.po and bricks.pot.

Any Idea what I’m doing wrong?

Help would be greatly appreciated
Best regards Suat
