This option is an advanced feature that allows direct manipulation of the running browser using Python code. You can also customize variables in the entire execution environment and perform operations such as modifying and assigning values. Here are some examples:
1. Use `self.browser` to refer to the current browser being operated. You can directly use Selenium's API to perform operations, such as `self.browser.find_element(By.CSS_SELECTOR, "body").send_keys(Keys.END)` to scroll to the bottom.
