test shows it can be "bar" | undefined how can I make it be just "bar" ?

my only solution i could find is to put Foobar into Required, like this:

const test = "whatever" as unknown as Required<Foobar>["foo"];

is this the right way?

NonNullable<> works too

Hm, it actually doesnt?

NonNullable over the nullable thing, NonNullable<FooBar["foo"]>
