geom_GeomFlow() not implemented

[NMaziak]

Hello, I wanted to make a geom_flow ggplot interactive but got the error that it has not yet been implemented. That would be really appreciated if it could be!

A brief summary. of my code, I also use geom_stratum()

ggplot(df,
       aes(x = x, stratum = place, alluvium = group,
           y = n)) +
  geom_flow() +
  geom_stratum()
