how to calculate mdape in R

I want to use mdape() function to get median absolute percentage error in R, but it says :

could not find function "mdape" 

I use Metrics library, and it works for median absolute error

I'm not sure if there exists mdape function in Metrics package.

I found cognitiveutils::MDAPE() and prophet::performance_metrics(df, metrics = 'mdape', rolling_window = 0.1)

Try(cognitiveutils)

install.packages("remotes") remotes::install_github("JanaJarecki/cognitiveutils") cognitiveutils::MDAPE() 

or(prophet)

install.packages("prophet") prophet::performance_metrics(df, metrics = 'mdape', rolling_window = 0.1)
