Digging myself deeper in documentation I got the following result.

There is a way to group your custom blocks around a given category in Gutenberg, and therefore we have the method block_categories_all. So with a filter you can extend the default categories with custom ones.

Here is my example:

add_filter( 'block_categories_all', function( $categories, $post ) {
    return array_merge(
        $categories,
        array(
            array(
                'slug'  => 'my-slug',
                'title' => 'my-title',
            ),
        )
    );
}, 10, 2 );
