Brownfield navigation: Object params are generated as `Any` in native code

[Doko-Demo-Doa]

Hi Callstack team, we have been working with brownfield navigation library, but bumped onto this (issue?). For example, the brownfield.navigation.ts spec is:

export type DummyType = {
  testParams: string;
};

export interface BrownfieldNavigationSpec {
  test(arg: DummyType): void;
}

the generated native code (e.g: Swift) will be:

import Foundation

@objc public protocol BrownfieldNavigationDelegate: AnyObject {
    @objc func test(_ arg: Any)
}

Is this intended behavior? How can we generate type-safe code? Considering DummyType is just normal, serializable Javascript object.
