Customize RAK5010 firmware

Good morning,

I would like to customize the RAK5010 firmware, so i followed this link :
https://forum.rakwireless.com/t/rak-online-compiler-for-you-to-compile-your-customized-firmware-based-on-rui/662/38
But it tells me “Oops! That page doesn’t exist or is private.”

What should I do?

Thank you
