Problem in the "While" loop: the list of a page with Selenium does not scroll down

A personal study purpose for my learning, I'm creating this short script which is meant to open a link to a Facebook post and click all the "Add Friend" buttons while the scroll bar scrolls through the list. To avoid spam, I added the ability to choose the maximum number of people to add and the time between requests.

I have the executable and complete code (published at the end of the question), but there is something wrong. How can I scroll down the list and at the same time click on the "Add friend" buttons in relation to the settings to choose the maximum number of people to add and the time between one request and another?

(SCROLL DOWN CORRECTLY) If I just write, like this, then the scrollbar goes down

i = 1

while True:
i = i + 1

row = wait.until(EC.visibility_of_element_located((By.XPATH, f"(//div[@data-visualcompletion='ignore-dynamic' and not (@role) and not (@class)])[{i}]")))

driver.execute_script("arguments[0].scrollIntoView(true);", row)

(NOT SCROLL DOWN CORRECTLY) While, for example, if I add the staves to click on all the buttons, the scroll bar no longer drops (click automatically only on the first "Add friend" button, so you don't click on the following ones, I would also like to click on the following buttons)

wait = WebDriverWait(driver, 30)
i = 1

while True:
i = i + 1

row = wait.until(EC.visibility_of_element_located((By.XPATH, f"(//div[@data-visualcompletion='ignore-dynamic' and not (@role) and not (@class)])[{i}]")))
add = WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//span[text()='Add friend']"))).click()
close_popup = WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//span[text()='Ok']"))).click()

driver.execute_script("arguments[0].scrollIntoView(true);", row, add, close_popup)
