As topic, I make a mistake to drop the onboarding_db just now, so can I get onboarding_db again, and how to get it? thank you.
Hey @aa80460103!
If you write to support via the chat option in your app and authorize us to step into your app we can recreate those resources for you 
Additionally, if you haven't already, you might want to consider signing up for the Retool Database beta!
