Built-In De-esser

Hello, I’m a newbie i’m afraid but a willing learner. It’s

I have Cubase LE 8 and I’d like to de-ess my main vocals but I can’t seem to find a De-esser under the dynamics setting. Is there a built-in de-esser and if so how do I access it?

If not, which cheap de-essers are available out there?

Thanks in advance

Cubase pro only, although I presume LE has the channel strip which has a de-esser.
