I just made a quick video and uploaded it to YouTube showing my new 2021 X5 xDrive45e using my Tesla Wall Connector.
Using this adapter for the Tesla to J-1772 connection.
This adapter is great for all X5 45e owners to buy regardless, because there are thousands of these Tesla wall connectors all over the place in useful destinations. Tesla calls them "Destination Chargers". And they are free. At most you have to pay valet parking fees at hotels, which you would likely pay regardless.
