StripeTerminal.collectPaymentMethod erroring with "A required parameter was invalid or missing"

Describe the bug
I have followed the instructions in the readme here and I consistently get the following error:

{"errorMessage":"A required parameter was invalid or missing.","message":"A required parameter was invalid or missing."}

My code is as follows:

const paymentIntentResponse: { response: HttpResponse; status: string } = await createTtpPaymentIntent({
  invoiceId: invoiceStore.invoice.id,
  amount: selectedPaymentAmount.value,
  tipAmount: selectedTipAmount.value,
});

// paymentIntent is in this format `pi_***_secret_***`
const { client_secret: paymentIntent } = (paymentIntentResponse.response as HttpResponse).data;
// Show the Stripe Tap-To-Pay screen
const paymentMethodRes = await StripeTerminal.collectPaymentMethod(paymentIntent);
// Error returned: {"errorMessage":"A required parameter was invalid or missing.","message":"A required parameter was invalid or missing."}

I have tried passing in pi_*** as well as pi_***_secret_*** and both give the same error: "A required parameter was invalid or missing."

What am I missing here?

Thank you in advance.

Additional context:
I have tried using v6.4.1 and v6.2.1, both are producing the same error on iOS and Android.

Expected behavior
The tap to pay screen appears allowing you to take payment.

Using Function:

• Payment Sheet / Payment Flow
• Apple Pay
• Google Pay
• Identity (@capacitor-community/stripe-identity)
• Terminal（@capacitor-community/stripe-terminal）

Closing this as my issue was related to not passing in onBehalfOf param when connecting to a reader. Passing that in fixes this issue.
