FeathersJS TypeScript hook returning boolean

I'm trying to create a FeathersJS hook that returns a boolean value to use inside the iff() hook of the "feathers-hooks-common" package. Something like the isProvider() hook of the same package.

My problem is that I'm using the TypeScript version of the feathers cli generated app and when I use the generator to create a new hook, the result is:

// Use this hook to manipulate incoming or outgoing data.
// For more information on hooks see: http://docs.feathersjs.com/api/hooks.html
import { Hook, HookContext } from '@feathersjs/feathers';

// eslint-disable-next-line @typescript-eslint/no-unused-vars
export default (options = {}): Hook => {
  return async (context: HookContext): Promise<HookContext> => {
    console.log(context);
    return context;
  };
};

so I don't know how can I use this generated typescript code to return a boolean value that can be used in the iff() hook.

Is there anyone that knows how to do this?

Thank you!

if anybody needs it, I've used this code to return a boolean value in a hook:

    // Use this hook to manipulate incoming or outgoing data.
    // For more information on hooks see: http://docs.feathersjs.com/api/hooks.html
    import { HookContext } from '@feathersjs/feathers';
    
    // eslint-disable-next-line @typescript-eslint/no-unused-vars
    export default (options = {}) => {
      return async (context: HookContext): Promise<boolean> => {
        //Do whatever you need with context data
        return a_boolean_value;
      };
    };

I don't know if this would be "the FeathersJS way" but it works.
