Vue: How to mock Auth0 for testing with Vitest

I am trying to test a Vue component with Vitest but in order to do that I need to mock auth0

Below is my Navbar.test.ts file, however when I run the test I keep getting the following error Cannot read properties of undefined (reading 'mockReturnValue' as useAuth0 seems to be undefined even though I am imported it at the top of the page. Maybe I'm just not understanding the mocking side of it very well but any help would be appreciated.

import { vi } from 'vitest'
import { ref } from "vue";
import { shallowMount } from '@vue/test-utils'
import { useAuth0 } from '@auth0/auth0-vue';
import NavBar from "@/components/NavBar.vue";

const user = {
    email: "user@test.com",
    email_verified: true,
    sub: ""
};

vi.mock("@auth0/auth0-vue");

const mockedUseAuth0 = vi.mocked(useAuth0, true);

describe("NavBar.vue", () => {
    beforeEach(() => {
        mockedUseAuth0.mockReturnValue({
            isAuthenticated: ref(true),
            user: ref(user),
            logout: vi.fn(),
            loginWithRedirect: vi.fn(),
            ...
            isLoading: ref(false),
        });
    });

    it("mounts", () => {
        const wrapper = shallowMount(NavBar, {
            props: { },
        });

        expect(wrapper).toBeTruthy();
    });

    afterEach(() => vi.clearAllMocks());
});
