How do you integrate Selenium with Rest Assured for API + UI hybrid testing?

@Test
public void verifyProductAppearsOnUI() {
    // FAST: Create test product via API (no UI navigation)
    String productJson = "{\"name\":\"Test Widget\",\"price\":99.99,\"stock\":10}";
    Response apiResponse = RestAssured
        .given()
        .header("Authorization", "Bearer " + getAuthToken())
        .contentType("application/json")
        .body(productJson)
        .post("https://api.automateqa.online/products");

    Assert.assertEquals(apiResponse.statusCode(), 201);
    String productId = apiResponse.jsonPath().getString("id");

    // THOROUGH: Verify it appears correctly in the UI
    driver.get("https://automateqa.online/products/" + productId);
    Assert.assertEquals(
        driver.findElement(By.cssSelector(".product-title")).getText(), "Test Widget");
    Assert.assertEquals(
        driver.findElement(By.cssSelector(".product-price")).getText(), "$99.99");
}

@BeforeClass
public void loginViaAPI() {
    // Fast API login — no UI login form navigation
    Response response = RestAssured
        .given()
        .body("{\"email\":\"admin@test.com\",\"password\":\"pass123\"}")
        .contentType("application/json")
        .post("https://api.automateqa.online/auth/login");

    String token = response.jsonPath().getString("token");

    // Inject auth as cookie in browser
    driver.get("https://automateqa.online");
    driver.manage().addCookie(new Cookie("auth_token", token));
    driver.navigate().to("https://automateqa.online/dashboard");
    // Now on dashboard — skipped entire login UI flow
}

@Test
public void verifyDashboardStats() {
    // UI test — already authenticated via API
    Assert.assertTrue(
        driver.findElement(By.cssSelector(".welcome-message"))
              .getText().contains("Welcome"));
}

@Test
public void submitOrderViaUIVerifyViaAPI() {
    // UI: Place order
    driver.get("https://automateqa.online/cart");
    driver.findElement(By.id("checkoutBtn")).click();
    driver.findElement(By.id("confirmOrder")).click();

    String orderId = driver.findElement(By.cssSelector(".order-id")).getText();

    // API: Verify order created correctly in backend
    Response orderResponse = RestAssured
        .given()
        .header("Authorization", "Bearer " + authToken)
        .get("https://api.automateqa.online/orders/" + orderId);

    Assert.assertEquals(orderResponse.statusCode(), 200);
    Assert.assertEquals(orderResponse.jsonPath().getString("status"), "CONFIRMED");
    Assert.assertEquals(orderResponse.jsonPath().getFloat("total"), 149.99f, 0.01f);
}

@AfterMethod
public void cleanupTestData(ITestResult result) {
    if (createdProductId != null) {
        // Clean up via API — faster and more reliable than UI deletion
        RestAssured
            .given()
            .header("Authorization", "Bearer " + authToken)
            .delete("https://api.automateqa.online/products/" + createdProductId);
