mock a service with Jest

Trying to write a test to provide code coverage for the following code :

note : there are other functions in the service but just listing one for brevity.

export const service = {
     getById: async (id) => {
     const url = `/api/customers/${id}/names`
     const {data} = await axios.get(url, axiosOptions);
     return data;
}

I'm attempting to simply provide code coverage with this test:

note : I have attempted to use require instead of import but that does not seem to work.

import {service} from './requests';

it("mocks the getById function", () => {
     service.getById = jest.fn();

     expect(service.getById.mock).toBeTruthy();
}

This test passes however seems to provide no code coverage.

I've attempted to mock out the axios call but I seem to get nowhere as examples I've found of implementations are not working for me currently.

Does anyone have ideas and an example how I could provide code coverage for the service please?

Update : to sonEtLumiere's answer

jest.mock('./service', () => ({
     getById: jest.fn().mockResolvedValue({ data : "hello"}),
}));

describe('test', () => {
     it('mocks the service", async () => {
     service.getById.mockResolvedValue({data: "hello});
     const data = await service.getById(1);
     expect(data).toEqual({data:"hello"});
   })
})

Currently getting back error :

Cannot read properties of undefined (reading 'getById')

Any thoughts on why I'm getting this error?
