Describe the bug

it's not a bug but i want to make a composable like useFetch in nuxt with type-safe IntelliSense When I extend the Fetch options I get intellesense with this type body?: ((BodyInit | Record<string, any> | null) & Product) | undefined and a lot of properties that I don't need so I try to omit the body from the fetch options to get the property I need only but I got error on the $fetch function

Argument of type 'Options<R, M>' is not assignable to parameter of type 'FetchOptions<any> | undefined'.
  Type 'Options<R, M>' is not assignable to type 'FetchOptions<any>'.
    Types of property 'body' are incompatible.
      Type '(Body<R, M> extends never ? undefined : Body<R, M>) | undefined' is not assignable to type 'BodyInit | Record<string, any> | null | undefined'.
        Type 'Body<R, M> extends never ? undefined : Body<R, M>' is not assignable to type 'BodyInit | Record<string, any> | null | undefined'.
          Type 'Body<R, M> | undefined' is not assignable to type 'BodyInit | Record<string, any> | null | undefined'.
            Type 'Body<R, M>' is not assignable to type 'BodyInit | Record<string, any> | null | undefined'.
              Type 'unknown' is not assignable to type 'BodyInit | Record<string, any> | null | undefined'.
                Type 'Body<R, M>' is not assignable to type 'URLSearchParams'.
                  Type 'unknown' is not assignable to type 'URLSearchParams'.
                    Type 'Body<R, M> extends never ? undefined : Body<R, M>' is not assignable to type 'URLSearchParams'.
                      Type 'Body<R, M> | undefined' is not assignable to type 'URLSearchParams'.
                        Type 'undefined' is not assignable to type 'URLSearchParams'.ts(2345)

this is my code below

import type { Api } from "~/ERP-Configs/types/api"
import { FetchOptions, $fetch } from "ohmyfetch";

type Request = keyof Api;

type Method<R extends Request> = keyof Api[R];

type Body<R extends Request, M extends Method<R>> = Api[R][M] extends {
    BODY: infer B;
} ? B : never;

type Return<R extends Request, M extends Method<R>> = Api[R][M] extends {
    BODY: any; RETURN: infer P
}
    ? P
    : Api[R][M] extends { BODY: any }
    ? void
    : Api[R][M];

type Options<R extends Request, M extends Method<R>> = Omit<FetchOptions,'body'> & {
    method: M;
    body?: Body<R, M> extends never ? undefined : Body<R, M>;
}

const useApi = <R extends keyof Api, M extends Method<R>>(
    request: R,
    options: Options<R, M>
): Promise<Return<R, M>> => {
    return $fetch(request, options)
};

export default useApi;
