How to use the JSON field in database?

Hi!

I created a JSON field in the database manager, and created variables within. Each variable has the appropriate label and input in the ui properties.

The form generator didn’t create the fields though.

Not sure if this is a bug or if I’m not using it correctly, probably the latter.
Would appreciate more tutorials on this as I think this feature is really useful for complex user / app settings and configurations.
