How to define types for jsonb

How do you provide custom type interfaces for jsonb columns returned via queries.

for instance if i have a column:

myfield: jsonb('data').notNull()

myfield: jsonb('data').notNull()

myfield: jsonb('data').notNull()

myfield: jsonb('data').notNull()

i want to be able to define a type interface for

myfield

myfield

myfield

myfield such that when i do

const { myfield } = await db.query.myTable.findFirst({})

const { myfield } = await db.query.myTable.findFirst({})

const { myfield } = await db.query.myTable.findFirst({})

const { myfield } = await db.query.myTable.findFirst({}), the type of myfield is customized instead of

unknown

unknown

unknown

unknown

im aware of this page in the docs (https://orm.drizzle.team/docs/custom-types) but i think this is not actually for what im talking about but maybe im dumb
