Load Testing Rstudio Connect

Hello! Recently, we have started using Rstuido Connect and we want to migrate our web application to this platform. But first thing firts, fault tolerance and perfomance is our priority. According to Rstudio Connect User guide we can perform load testing with shinyloadtest+shinycannon (Shiny - RStudio Connect: User Guide). But, official guideline of the shinyloadtest says we actualy can't (Limitations of shinyloadtest • shinyloadtest). The question is, what tool should we use for load testing Rstudio connect ?
