When creating user tours you can choose to place it on the page using css code by selecting "Selector" as target type. In the CSS field you are then supposed to reference the right place on the page by using css class names. In the text box "CSS-selector" the help text says "A CSS selector can be used to target almost any element on the page. The appropriate selector can be easily found using the developer tools for your web browser." What exactly does this mean? I've tried using the class name for example the home menu item but it just won't work. 

Can someone as Totara supply an example of what you put in that box in the example in the help documentation for User tours?

We have tried to get these classes to work:

"totara-menu-nav-item menu-home first"

"flex-icon ft-fw ft fa-home"

What, exactly, should we put in the CSS field?
