Use of shinytest2 whith shinyproxy

We would like to test our app in production which is running with ShinyProxy with shinytest2 (Posit).

Until now, all our tests have been performed using Selenium which was working fairly well but to us shinytest2 looks more promising as it is really dedicated to Shiny.

However, once the headless chrome browser of shinytest2 is correctly connected to the app, the ShinyProxy layer on top of the app seems to interfere with the queries of shinytest2 and it cannot interact with the app anymore.

Do someone have a little experience with shinytest2 (working with ShinyProxy).

Kind regards,
