Hi,
I already asked the support about this and got the following answer:
Thank you for contacting Bambu Lab support team!
The items which are contained in the early bird gift will be available for sale in our store in the future, ETA will be around April. The camera of the X1 is for X1 series exclusive, it does not work with P1P.Feel free to let us know if you have any other questions.
Have a good day!
I guess we have to wait until April
