To enter Pairing Mode on the micro:bit you'll need to hold down  the A, B and reset buttons simultaneously, then release the reset button once the LED screen has filled and you see the Bluetooth logo.


Ensure you have flashed a new/recently created HEX file to the micro:bit created in makecode.microbit.org. It doesn't necessarily matter what the program does, but a new file will contain the latest pairing process as part of the HEX.
