EnrollmentExchangeTokenQrCode
A single short-lived QR code token for App-2-App enrollment, as returned in the list by com.futurae.sdk.public_api.operations.FuturaeOperationsApi.getEnrollmentExchangeTokens.
The host app should display the tokens one at a time, always switching to the next one before the current token expires, so the new device can scan and complete the enrollment.
