The intention is to perform a single click at (x, y). I did try this method found on internet.
tell application "System Events"
tell process "X"
click at {350, 50}
end tell
end tell

"X" would be the process that you want to perform the click (ex. Safari, Finder, etc). I've found that it can also be omitted.
tell application "System Events"
click at {0, 0}
end tell
This should activate the Apple menu in the top left. You can use the crosshairs from the screenshot tool (⌘ + ⌃ + ⇧ + 4) to determine coordinates of objects on your screen. If the application needs to be active beforehand you can do something like
tell application "System Events"
tell process "Safari"
activate
click at {20, 40}
end tell
end tell
