Can't find Special Effect - Color Transform Tool

I just started to learn animating and want to make fadeout effect. From tutorial I should go from Element - New Element - Color Tranform tool. But there’s no Element Menu in my Toonboom Harmony. Also can go from Add from my timeline - Color Transform Tool But can’t find it either. Advice ?

If you’re using Harmony Essentials or Advanced.
https://docs.toonboom.com/help/harmony-15/advanced/reference/node/filter/transparency-node.html?Highlight=Transparency

If you’re using Harmony Premium.
Add a Transparency Node from the Node Library to your Layer and animate the Transparency.

Thanks !! I’ve added the Transparency from Node view, any it works now
