How to use the tipsi-stripe.confirmPaymentIntent function in tipsi-stripe

// The initial confirm did not require_action - a new payment method is required instead.
          response = confirmResult
        }
        this.setState({ ...this.state, loading: false, display: response })
      }
    } else if (this.state.confirmationMethod === 'automatic') {
      // Here we're in automatic confirmation mode.
      // In this mode, we can confirm the payment from the client side and
      // fulfill the order on the client side by listening to webhooks.

      // For cards, we also get immediate confirmation of the outcome of the payment.

      let display = null
      try {
        console.log('Confirming')
        const confirmPaymentResult = await stripe.confirmPaymentIntent({
          clientSecret: this.state.paymentIntent.secret,
          paymentMethod: demoPaymentMethodDetailsWithCard(cardNumber),
        })
        display = confirmPaymentResult
      } catch (e) {
        // One way we can arrive here is if the payment intent had previously succeeded.

        console.dir(e)
        display = {
          message: e.message,
          code: e.code,
        }
      }
      this.setState({ ...this.state, loading: false, display })
    }
  }
