Script call for mouse clicks

[Name]

What is the script call for left mouse button click? Like if I wanted something to do something when you click on it with the mouse. I don't want a plugin, just a script call for a conditional branch.

The left mouse button is the same as the 'ok' button. So I think you can just use Input.isTriggered('ok') or Input.isPressed('ok').
