Customer’s payment method not saved

Hello,

When a payment is made through Stripe, I want the customer’s payment method information data to be saved on Stripe. You gave me this code a few months ago, which works fine:

add_filter('wc_stripe_force_save_payment_method', function($bool){

if(is_checkout()){

$bool = true;

}

return $bool;

});

However, if the customer chooses to pay through Klarna, the customer’s payment method information data is not saved on Stripe.

Could you please tell me how to do to have the customer’s payment method information data saved for both payment by Stripe or Klarna ?
