I'm fine with using the key fob to open the frunk, but found this interesting; three ways to open the frunk and four ways to close it.
From the manual, three options to open the frunk:

Apparently there is a close button on the front edge of the hood.
This isn't the interior hood interior emergency release button, which is located inside the frunk.
So, the close button on the front edge of the hood can be used to close the frunk, but not open it?
This close button must cause the hood to start moving down and then possibly cause the "power auto-cinch" mechanism to pull the hood closed (stated in the "Manually Closing The Hood" section").
Perhaps that close button is on the inside front edge of the hood and therefore inaccessible when the frunk is closed and therefore can't be used to open the frunk.
Kind of like the liftgate button is tucked under the rear lift gate area, near the license plate.
