TouchID button customisation

Hello, I'm wondering if the Touch ID button could be customised - it's clickable, so I'd like to create a BTT shortcut that locks/unlocks my Mac on click

I think the touch ID functions as a power button, so it wouldn't be wise to change the function of that button. Because of that, I'm pretty sure there is no way possible to program the touch ID button. The only thing that the touch ID button can be used for is accessibility options (triple click the touch ID button)
