Finally found a fork of @orklann’s gamepad extension above by @fdalvi, which worked with both buttons and axes on the micro:bit V1.5/FW0249 as a controller over Bluetooth for MakeCode Arcade games running in the browser(school chromebook in my case):
Had to compile with an older version 3.1.4 of the micro:bit MakeCode editor:

Tested with @LuayBenAlaya’s “Button tester”:

Thank you very much, @fdalvi!!!
PS: Here’s a quick implementation of the controller logic for the micro:bit, anyone’s interested in trying it out quickly:
