This is NOT correct. The new X Refresh fobs 100% operate the doors. They changed the button presses though. Recommend you watch this Tesla video which explains it.
2016 - 2020 button presses are DIFFERENT than the 2021 and later.
Check out this video for X Refresh.

For folks who didn't watch the video, since I did and picked up my X Refresh TODAY!
Double press roof of fob for driver door open. Double press again of fob for passenger door. This is SEPARATE from Falcon Doors control on fob.
