Some frontend frameworks will refuse clicks from the user if the element clicked on is not visible. Here is a little trick that ensure the element is in fact visible, by scrolling down below it then scrolling back up a bit, before you do click on it using your robot.
el = find_element() # replace this by whatever element finder you need
browser.execute_script("arguments[0].scrollIntoView(true); window.scrollBy(0, -120);", el)
