How to use the d3-force.forceManyBody.mockImplementation function in d3-force

beforeEach(() => {
                const fr = 10;
                const forceStub = jest.fn();

                d3ForceX.mockImplementation(() => ({ strength: () => fr }));
                d3ForceY.mockImplementation(() => ({ strength: () => fr }));
                d3ForceManyBody.mockImplementation(() => ({ strength: () => fr }));
                forceStub.mockImplementation(() => ({ force: forceStub }));
                d3ForceSimulation.mockImplementation(() => ({ force: forceStub }));
                utils.merge.mockImplementation(() => ({ config: "config" }));
            });
