I am having problems with clicking an element in a dropdown. What i have to do is:

1. Open https://pastebin.com
2. paste "Hello from WebDriver"
3. Set Paste Expiration to "10 Minutes"
4. Set Paste Title to "helloweb"

However, after opening the dropdown some 3rd party ad content doesn't let me click my button, which results in ElementClickInterceptedError

Here is my code

const {Browser} = require('selenium-webdriver');
const {Builder, By, Key, until} = require('selenium-webdriver');

(async function example() {
  let driver = await new Builder().forBrowser('chrome').build();
  driver.manage().window().maximize();

  try {
    await driver.get('https://pastebin.com');
    await driver.findElement(By.xpath('//*[@id="postform-text"]')).sendKeys('Hello from WebDriver');
    await driver.findElement(By.xpath('//*[@id="w0"]/div[5]/div[1]/div[2]/div/span/span[1]/span')).click()
    await driver.findElement(By.xpath("//*[@id=\"select2-postform-expiration-results\"]/li[3]")).click();
    await driver.findElement(By.xpath('//*[@id="postform-name"]')).sendKeys('helloweb');

  finally {
    // await driver.quit();
  }
})();

The error message im getting:

ElementClickInterceptedError: element click intercepted: Element <span class="select2-selection select2-selection--single" role="combobox" aria-h
aspopup="true" aria-expanded="false" tabindex="0" aria-disabled="false" aria-labelledby="select2-postform-expiration-container">...</span> is not
