So, today, I found a person(change-agent) telling about the fact that GAUDC does allow personal requests. But it was complicated so I made a guide.
Actually, the Google Assistant SDK used by GAUDC was changed to remove personal results but by reengineering it, people in the GAUDC community figured out how to allow personal results.
This is the advanced guide and if you want the real one, hit this and if you want the original, click here. Thanks to morgenman
and change-agent
for that reply that helped me to make this!
