How to use query editor in custom module?

I’m trying to extend paged query to allow user to filter on multiple columns in table.

I extended paged query and I’m looking for the hjson of the Wappler paged query to stick as much as possible as the original, but I can’t find if it’s possible to have the query editor as the original database query modules.

EDIT: For the dropdown of database connections I don’t know if we can have that too in custom modules?
