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!
I'm attempting to set this up, and followed all the steps exactly, but I'm still encountering the issue where it'll still ask me for personal results, even after I've set it on my phone (and I already tried making a new project in the actions console, where I enabled Account Linking immediately)
