How to get around a limit in an R function?

I am doing data analysis on the Acadie portal in fr.wikipedia.org.

I am using WikipediR::pages_in_category to make a list of the pages in the portal:

library(WikipediR)
portal_acadie <- pages_in_category(language = "fr", 
                                    project = "wikipedia", 
                                    categories = "Portail:Acadie/Articles liés", 
                                    limit = 500, 
                                    clean_response = TRUE)

There is a limited output of 500 to the function, but I know the portal has 1900+ pages. How can I extract the remaining 1400+?

I tried changing the limit argument to limit = 2000, but I had a warning message indicating

'"cmlimit" may not be over 500 (set to 2000) for users.'

It only showed the first 500 pages.
