Now you have me a bit worried. The oriental specifications for this device are sketchy at best.
It seems to contain 3 switches, 3 resistors and have 8 pins.
Connecting both ground and 3.3V from the Pico to this device without a proper diagram runs the risk of shorting 3.3 to ground and popping the fuse on the Pico, A Bad thing :(
If you have an ohmmeter that would provide a way to probe the device safely and figure out how it is wired. Short of that connect ground only and not the 3.3V. use the pin setup with pull up. The code that reads a Pico pin to light the LED can then be used as a test probe to puzzle out a proper wiring sequence.
