facebook prophet - making a monthly cross validation using fbprophet library in R

Question

I'm trying to do a monthly time slice cross validation in R using the fbprophet library. Basically, I'm having n months with different values and I want to make a loocv (backtesting with period 1). Here's my code

m <- prophet(monthly_oc_df)
cross_validation(
  m,
  initial = 1,
  period = nrow(monthly_oc_df)
)

How can I accomplish that?

Thanks in advance!
