A legend with a subset of a dynamic layer

[ionarawilson1]

What would be the expression to just show a subset of a dynamic layer in a legend?
The layers property seems to be a good option but how do I use it?

For example if I have myLegend.layers = [dynamicLayer],

How do I change the expression to show only the first two or the last two layers of a service containing 4 layers?

Thank you!!!

use visibleLayers property

dynamicLayer.visibleLayers = new ArrayCollection([0, 1]);
