Not possible. Same as with any other webshop allowing ordering as a guest, in case you create a personal account later: Your earlier purchases as guest won‘t ever appear in your order history after login with your newly created account.
Check your confirmation mail with the QR code again… some date and the itinerary should appear amongst other info somewhere on the PDF right next to that QR code.
The actual PDF looks exactly the same, regardless whether you ordered it as guest or with your account.
