So basically I have a web page, and a couple of HTML buttons on it. On one of them I'd like to perform a mouse click. I know this button's class name, so basically I want to click on it by its class name. I know how to get the class name but I don't know how to click on this element, maybe there is a click function or something I don't know anything about.

I'm using 

```
var element = document.getElementsByClassName('hidden-xs truncate');
element.Click();

```

but i don't know what to do next, how to perform the click, can you help me with that?

`element.Click();` method doesn't work, I get the error:

> element.Click is not a function
