Hi,
I don’t understand really what do you search to do

recipes are based from ~/MagicMirror/modules/MMM-GoogleAssistant/recipes (like the current path)
now why ../../EXT-YouTube/recipe/EXT-YouTube.js ?

it will invoque to go EXT-Youtube directory, recipe in this directory and finaly open EXT-YouTube.js file
for verify;

cd ~/MagicMirror/modules/MMM-GoogleAssistant/recipes cat ../../EXT-YouTube/recipe/EXT-YouTube.js

and magical… recipe of youtube is displayed (from ~/MagicMirror/modules/EXT-YouTube/recipe/EXT-YouTube.js)

After, I don’t think that MMM-Pages Protocol is the same as EXT-Pages Protocol

Anyway, I don’t think it’s related to this topic.
