How to use position_jitter_tern() in ggtern() in R?

I am creating a simple ternary plot.

ggtern(data=data.frame(x=c(0.1,0.1),y=c(0.2,0.2),z=c(0.7,0.7)),aes(x,y,z)) + geom_point()    

How can I jitter the point so that the plot will display two points? I tried using position_jitter_tern like so: but it isn't changing anything.

ggtern(data=data.frame(x=c(0.1,0.1),y=c(0.2,0.2),z=c(0.7,0.7)),aes(x,y,z, position_jitter_tern(0.1,0.1,0.1))) + geom_point()
