Joins reactibble function doesn't work

[brianmsm]

I don't quite understand why it doesn't work

library(dplyr)
library(reactibble)

full_join.reactibble(
  as_reactibble(iris) %>% 
    select(Species, Sepal.Length),
  as_reactibble(iris) %>% 
    select(Species, Sepal.Width),
  by = "Species"
)
#> Error in NextMethod(): no se especificó la función genérica
