examples for estimate_profiles() do not work when package = 'mplus'?

library(tidyLPA)
#> You can use the function citation('tidyLPA') to create a citation for the use of {tidyLPA}.
#> Mplus is not installed. Use only package = 'mclust' when calling estimate_profiles().

iris_sample <- iris[c(1:4, 51:54, 101:104), ] # to make example run more quickly

# Example 1:
iris_sample %>%
  subset(select = c("Sepal.Length", "Sepal.Width",
                    "Petal.Length")) %>%
  estimate_profiles(3, package = "mplus")
#> Error: Mplus variable names must start with an alphabetical character, and may contain numbers and/or the underscore character (_). Some of your variables violate this rule:
#>   Sepal.Length
#>   Sepal.Width
#>   Petal.Length
