Your car has ID7 "lite" and does not have remote Software Update (RSU). You have to get updates at the dealer. The attached matrix PDF shows that your car is compatible with Android Auto provided your software is at least 7/2020 and you have the Connected Package Professional (6C4). You can find your software version by opening the User Guide in the car and searching for the keyword IMPRINT. Right below you will see the version date. I had some trouble convincing my dealer that my car is entitled to have AA. I showed them this:

They kept the car for a week before they figured out what to do. Not only the car software has to be updated but the BMW servers have to be also configured to recognize your car. The dealer did this under warranty. If you are out of warranty, you will have to pay.
Though the matrix shows N/A for Amazon Alexa, I was able to activate Alexa. See the other two attachments.
Good luck
