MakeCode Arcade on Recalbox

Hello,
Many thanks for all your work regarding MakeCode Arcade integration in RecalBox.
I just have some try but for the moment without any success :frowning:
I am trying to follow the link below :

" Run this command from the terminal(F4 + ALT+F2, root/recalboxroot) on Recalbox 7.1.1-Reloaded!:
curl -sL https://raw.githubusercontent.com/Vegz78/McAirpos/master/install_recalbox.sh | bash -"

Is it possible to have more details please?

Regards.
