setState(value) not being recognized as proper input by TypeScript

[skokenes]

I have a value that is of type Profunctor:
const testProf = useProfunctorState("foo");

With this setup, I have no problem updating the state with function, like
testProf.setState(() => "bar")

However, if I try to use a new value instead of a function, TypeScript throws an error. For example, if I write testProf.setState("bar"), TypeScript says "Argument of type '"bar"' is not assignable to parameter of type 'Updater'. "

I'm relatively new to TS so I am not sure how to fix this in the package source. Any suggestions would be appreciated.
