Hi, I changed a bit my taxonomy architecture.
The website i am working on sales shoes so I made a “Brand” category with “Nike, Adidas and so on…” the shoes models “air max, air force…” are saved as a children categories of the brand they belong to.

That way i no longer need to register_taxonomy if i want to add a new brand from my option page, i just have to insert a new term inside on the root of my “Brand” category.

Here is how i did it:

// run AFTER ACF saves the $_POST['fields'] data
add_action('acf/save_post', 'my_acf_save_option_page', 20);	

function my_acf_save_option_page( $post_id ){
    
    //getting the value of my text box
    $brand_to_add = get_field_object('field_52d6f9449e688', 'option');
     
    //Checking if the value is not empty (this also check if it exists 
    //so when i am saving a post and not the option page the 
    //wp_insert_term is not called
    if( !empty($brand_to_add['value'])){ 
        //inserting the desired value inside the "marque" category 
        //(marque = brand in french)
        wp_insert_term( $brand_to_add['value'], 'marque' );

    }//end if statement 
}

also when the option page is loaded the text field value is set to an empty string so we can add a new category

// Reset new brand field
add_filter('acf/load_field/key=field_52d6f9449e688', 'reset_new_brand');	

function reset_new_brand( $field ){
    // reset choices
    $field['value'] = '';
    
    // Important: return the field
    return $field;
}
