DR/ ManifoldLearning: How plot LEM

How can I plot the output object from LEM or LTSA in ManifolsLearning.jl ?

I tried to do

Y_LEM = transform(LEM,data_array; k=12, d=2, t=1.0)
Plots.scatter(Y_LEM, title="ManifoldLearning: Laplacian Eigenmaps")

But I get the error message

No user recipe functions defined for LEM.ManifoldLearning

Can anyone help? Thanks
