Selenium Drop Down

I am trying to learn Selenium. For my small project, I am trying to automate amazon shopping cart. My flow is simple:

1. Open amazon.com
2. Search a product
3. Select size
4. Add to cart.

I am getting an error on Select Size.

@Test(priority = 3, groups = {"Startshopping"})    public <T> void addItemToCart() throws InterruptedException {        System.out.println("::::addItemToCart");        // Navigate to the product page        driver.get("https://www.amazon.com/Speedo-Rubber-Swim-X-Small-Yellow/dp/B005FYF9MU/ref=sr_1_5?crid=3720YVMBX45Q6&dib=eyJ2IjoiMSJ9.y9eXnqIydahqg0WjO3ehKHM65sn9kbsKPyhIxHga-HIlCuf7zQlZnqY6FxkBOW7DL-5MpTHyDd2qZEbexu2biaX6rOlb_zQC_HxBog7hE2w2B56sqg9S6lNjLhjvhiqoT-5hhn0sxvw6o7wFIW0gtEOd1tLKD7LyYtOjyiLY0CsKpF6mP0Xzwng1s1tF5N32s2XNby9LFVRfDXwCdcv8o-8YghwuEPzTiUzxfMZ8Nrr5vMxNBKGHR2pjgVJL1mJSrPz7WKaVkrRDFrzNGbKlUA7xM-fB1IDnRFHcGIuTzFU.nxFQ-aNfenY6irxxGenpBoDDaUxwWQLI3DDwCnItVrk&dib_tag=se&keywords=swimming%2Bfins%2Bxs&qid=1724391120&sprefix=%2Caps%2C73&sr=8-5&th=1");        //dp = driver.findElement(By.id("wpj3eu-brkvgc-dqr1de-o8f8rv"));        WebElement dp = new WebDriverWait(driver, Duration.ofSeconds(10))                .until(ExpectedConditions.elementToBeClickable(By.id("dropdown_selected_size_name")));            // Perform actions on the element        dp.click();        Select select= new Select(dp);        //select.selectByIndex(3);        //driver.findElement(By.id("add-to-cart-button")).click();    }

Any pointers?

I expect my code should select the drop down and select one of the options.
