Python Selenium By raises AttributeError: type object 'By' has no attribute 'XPATH'

Question

I have a problem with Selenium.

def main_test():
    chrome_options = Options()
    prefs = {"download.default_directory": f"{os.getcwd()}/Music"}
    chrome_options.add_argument("user-data-dir=selenium")
    chrome_options.add_experimental_option("prefs", prefs)
    dr = webdriver.Chrome(options=chrome_options, service=Service(ChromeDriverManager().install()))
    dr.get(URL)
    print(f"{selenium.__version__=}")
    dr.find_element(By.XPATH, "/html/body/div[1]/div[1]/div/div[1]/ul/li[2]/a").click()
    dr.quit()


if __name__ == '__main__':
    main_test()

This is my code. I think i followed properly the documentation. Although, when running the app i get this error:

selenium.__version__='4.6.0'
Traceback (most recent call last):
  File "/Users/andrea/Dev/Python/custom_scripts/ytchannel/main.py", line 142, in <module>
    main_test()
  File "/Users/andrea/Dev/Python/custom_scripts/ytchannel/main.py", line 137, in main_test
    dr.find_element(By.XPATH, "/html/body/div[1]/div[1]/div/div[1]/ul/li[2]/a").click()
AttributeError: type object 'By' has no attribute 'XPATH'

I have no clue on what i'm doing wrong... I can add every detail possible if needed.
