Lineart and colour art layers not visable?

I downloaded the free trail version of toon boom harmony a few days ago, and can’t seem to find the ‘art layers’ tool listed in the bar to the right.
I’ve seen multiple tutorials in which the concept o placed where it is supposed to bef art layers are brought up, and the tool doesn’t seem to be. I was wondering if there was a way to access it? I will try to attach a screenshot of the interface, and you should notice that the art layers tools are missing. (At least I believe they are.)

Thanks in advance for the help! I am very new to the program, so that is probably why I’m having a bit of trouble :slight_smile:

Art layers is not a feature available in Essentials.
