‘rvest’ package (R programming language) $click syntax for web scraping

I have a brief R script using the ‘rvest’ package and I cannot figure out how to click the “Begin Search” button based on the identified links.

library(rvest)
sess <- read_html_live("https://filingaccess.serff.com/sfa/home/CA")
sess$view()
links <- sess %>% html_elements("a")
