Inside the padded center console on our car was a package of two cellphone charging cables. One with an iPhone lightning connection and the other cable for android phones with their connector. We're an iPhone family so of course wanted two of the same kind. Swapping cables with someone else who's an android family works out well for all involved.
BTW in our glove box was a owners manual (yes! printed) and some other little booklet maybe warranty not sure. Also a zip lock bag with a metal wire in it. I asked about this and was told it was for your tire lug nuts I think. The Monroney sticker listing what you bought, options, price, VIN, eMPG or whatever it's called was placed behind our rear seats on the kind of trunk stationary parcel shelf. If you were a Day 1 line waiter and they still had any of the die cast Model 3 cars left, I've heard people found them in their cushioned center console section when they opened it up. Just read some people were still getting them (might depend on local store's supply).
Do check for your Mobile Connector in the square black zipper bag. Should be in your trunk area, believe ours was in the lower portion of the trunk, if not look for it in your frunk. Check to see you have the 3 adapters there--NEMA 14/50, J1772, and not sure what the third one was. The one thing I didn't look for was the Tow Hook. Hopefully don't ever need it but important to have in case you do. Have to remember to check for that. Might be in the trunk or frunk.
