Clicking a button found on different coordinates

I apologise for asking a simple question, but I would like to know how do I click a button if the coordinates are different?



In the attached picture below, I want to click on Logout, but some of the buttons are found in different coordinates since the users are of different types. As such, certain buttons are missing if the user is of a lower rank, which meant they have Logout nearer to the left.



Thanks for reading.
