What is the correct way to extend the express js

Question

What is the correct way to extend the express js

interface?
I have this route:

router.get('/', auth, async (req: AuthRequest, res: Response) => {

which use this interface

interface AuthRequest extends express.Request {
user: {
id: string;
}
}

for some reason I get:

No overload matches this call.
Overload 1 of 3, '(path: PathParams, ...handlers: RequestHandler<ParamsDictionary, any, any, ParsedQs>[]): Router', gave the following error.
Argument of type '(req: AuthRequest, res: Response) => Promise<void>' is not assignable to parameter of type 'RequestHandler<ParamsDictionary, any, any, ParsedQs>'.
Types of parameters 'req' and 'req' are incompatible.
Property 'user' is missing in type 'Request<ParamsDictionary, any, any, ParsedQs>' but required in type 'AuthRequest'.
Overload 2 of 3, '(path: PathParams, ...handlers: RequestHandlerParams<ParamsDictionary, any, any, ParsedQs>[]): Router', gave the following error.
Argument of type '(req: AuthRequest, res: Response) => Promise<void>' is not assignable to parameter of type 'RequestHandlerParams<ParamsDictionary, any, any, ParsedQs>'.
Type '(req: AuthRequest, res: Response) => Promise<void>' is not assignable to type 'RequestHandler<ParamsDictionary, any, any, ParsedQs>'.

what I did wrong? @TRGWII
