Don't have 'Styling'

Hi, I have just installed the Unyson plugin and activated it. I watched the video and it showed that the ‘styling’ tab should be under appearance. But mine is not there. 🙁
(‘Sliders’ came up fine but not ‘styling’)
Am I missing something? I looked in the extensions incase it needed to be added, but it’s also not there.
Thanks 🙂
