How to perform web scraping to get all the reviews of the an app in Google Play?

I pretend to be able to get all the reviews that users leave on Google Play about the apps. I have this code that they indicated there Web scrapping in R through Google playstore . But the problem is that you only get the first 40 reviews. Is there a possibility to get all the comments of the app?

`` `

#Loading the rvest package
library(rvest)
library(magrittr) # for the '%>%' pipe symbols
library(RSelenium) # to get the loaded html of 

#Specifying the url for desired website to be scrapped
url <- 'https://play.google.com/store/apps/details? 
id=com.phonegap.rxpal&hl=en_IN&showAllReviews=true'

# starting local RSelenium (this is the only way to start RSelenium that 
is working for me atm)
selCommand <- wdman::selenium(jvmargs = c("- 
Dwebdriver.chrome.verboseLogging=true"), retcommand = TRUE)
shell(selCommand, wait = FALSE, minimized = TRUE)
remDr <- remoteDriver(port = 4567L, browserName = "firefox")
remDr$open()

# go to website
remDr$navigate(url)

# get page source and save it as an html object with rvest
html_obj <- remDr$getPageSource(header = TRUE)[[1]] %>% read_html()

# 1) name field (assuming that with 'name' you refer to the name of the 
reviewer)
names <- html_obj %>% html_nodes(".kx8XBd .X43Kjb") %>% html_text()

# 2) How much star they got 
stars <- html_obj %>% html_nodes(".kx8XBd .nt2C1d [role='img']") %>% 
html_attr("aria-label")

# 3) review they wrote
reviews <- html_obj %>% html_nodes(".UD7Dzf") %>% html_text()

# create the df with all the info
review_data <- data.frame(names = names, stars = stars, reviews = reviews, 
stringsAsFactors = F)
