How to use a range of axes and labels from source data in ggtern?

Question

I use ggtern in R to make a triple plot, and would like to have axis labels and gaps in my ggtern plot, just like the original data. In the case of the generated data in the code below, each axis will reach a maximum of 12, 10 and 4.

Following the previous post, I tried to use gaps and labels for this, but each axis is still on the 0-1 scale, there are no labels (because of them more than 1), and axes with labels do not intersect the points on the graph. ( How to change the labels of the triple plot made by ggtern? )

library(ggtern)
labFnc <- function(x,digits=2) format(round(unique(x),digits),digits=digits)

mydata <- data.frame(
  x = runif(50, min = 0.25, max = 12),
  y = runif(50, min = 0.1, max = 10),
  z = runif(50, min = 0.5, max = 4),
  value = runif(50, min = 10000, max = 20000))

ggtern(data = mydata,aes(x = x, y = y, z = z,col=value)) + 
  theme_bw() +
  geom_point(alpha = 0.8, size = 3) +
  theme_showarrows() +
  scale_T_continuous(breaks=unique(mydata$x),labels=labFnc(mydata$x))+ 
  scale_L_continuous(breaks=unique(mydata$y),labels=labFnc(mydata$y))+ 
  scale_R_continuous(breaks=unique(mydata$z),labels=labFnc(mydata$z))

Is there any way to do this? Any help would be greatly appreciated.
