Mega2560 on a micro:bit using MakeCode

I am looking for the MakeCode extension block and all of the other information that should be on these webpages ( 2MP OV2640 Arducam Camera Module for Microbit - Arducam Wiki ) but are not.

Can anyone provide some advice on where to get and install the camera block extension to get the micro:bit up and running using MakeCode like it shows on this webpage ( Arducam Mini as A Micro:bit Camera ) ?

Greatly appreciated !
