Auto complete function for woocommerce not working?

Question

I am trying to auto complete order statuses for orders whose status is either pending or on hold. but the function is not working

add_filter( 'woocommerce_payment_complete_order_status', 'test_wc_autocomplete_paid_orders' );
function test_wc_autocomplete_paid_orders( $order_status, $order_id ) {
    
    $order = wc_get_order( $order_id );

    if ( $order_status == 'processing' && ( $order->status == 'on-hold' || $order->status == 'pending') ) {
        return 'completed';
    }
    
    return $order_status;

}

it is for payment through banks through stripe.

I tried woocommerce_thankyou action also. but still not working.

what I am doing wrong? it is for stripe sofort transfer.

thanks
