Mission/emergency critical buttons on dragon are physical (things like chute release) - there is a row of switches underneath the panel.

Looking at the left panel, I'm guessing you first select the function you want (Water Deorbit, Deorbit Now, Breakout, Depress Response, Suppress Fire, Fire Response), then click either Execute or Cancel. Lights on the switches help you know what is selected.
Looks like most car hazard light buttons.
If we're going to speculate based on a picture lets go with the most likely that the physical buttons do have tactile feedback lol.
That may be why it looks flat to me.
