Including arrows on the NMDS chart in R vegan package

I use the vegan package to build NMDS in R, analyzing the community features. It is based on a community matrix that includes various treatments:

NMDS=metaMDS(community_matrix,k=2,trymax=100)
plot(NMDS)

Can someone tell me how I can draw arrows to show how individual species respond to treatment?

Arrows would be a misinterpretation in such a plot; there is no reason to believe that in the plot, in which the dissimilarities of the samples of the ordinary order are best preserved, the view reacts linearly in this space.

We add the types that they would be in CA, as the weighted average number of points, possibly extended.
