As far as on that page Index element is placed in frame, you should use

driver.switchTo().frame("top");

before

driver.findElement(By.linkText("Index")).click();

where top is name attribute of your iframe.

Selenium by default uses top body level context and doesn't see elements in other contexts like iframes or shadow-roots. So to get him to know that you want to search for element in another context, you should change context Selenium is looking into.

And don't forget to switch to defaultContext() back when you returning to body context.

Use below line:

driver.switchTo().frame(0);

(0) - being the first frame on the HTML.

So your last 4 lines of code should be as below:

Thread.sleep(4000);
driver.navigate().forward();
driver.switchTo().frame(0);
driver.findElement(By.linkText("Index")).click();

Note: To switch back to default content, below line of code should be used:

driver.switch_to.default_content()

Within the website Test Pages For Automating once you click on the link with text as Frames Test Page and navigate to the Nested Frames Example page, the element with text as Index is within a <frame>:

frame

Solution

To click on the element with text as Index you have to:

Induce WebDriverWait for the desired frameToBeAvailableAndSwitchToIt.
Induce WebDriverWait for the desired elementToBeClickable.

You can use either of the following Locator Strategies:

ChromeOptions options = new ChromeOptions();
options.addArguments("--start-maximized");
WebDriver driver = new ChromeDriver(options);
driver.get("https://testpages.herokuapp.com/styled/index.html");
new WebDriverWait(driver, Duration.ofSeconds(5)).until(ExpectedConditions.elementToBeClickable(By.id("framestest"))).click();
new WebDriverWait(driver, Duration.ofSeconds(5)).until(ExpectedConditions.frameToBeAvailableAndSwitchToIt(By.name("top")));
new WebDriverWait(driver, Duration.ofSeconds(5)).until(ExpectedConditions.elementToBeClickable(By.linkText("Index"))).click();
