That's a similar method to the Tesla Model 3 and Y.

The S and X had motorized handles that retracted.

The Cybertruck has no physical handles on the outside. It has a button on the B pillar that activates an electric release to pop the door open.

All of those methods are flush, but only one isn't visible to rescuers and can completely fail with a lack of power or motor failure with no physical external backup option.
