Have access to files in client side when running app in shinyproxy

Hi, I have a shinyproxy server set up with two apps. One of this apps has the following code to access the files:

volumes = getVolumes()
volumes <- c(Home = fs::path_home(), "R Installation" = R.home(), getVolumes()())
file_selected <- reactive({
 shinyFileChoose(input, "file", roots = volumes, session = session)
 if (is.null(input$file))
 #print(parseFilePaths(volumes, input$file)$datapath)
 return(parseFilePaths(volumes, input$file)$datapath)

However this mapping does not work on the client side. This app is containerized in a docker, and when I click the file.selected button I can only see the files inside the docker. Is there any way to see the files in the client side?

For example, I am a user and type xx:xx:xx:xx:8080 and then I click on my app. When it loads, is there any way to see the files on my computer (locally), and of course this solution needs to be effective for all users that access the shinyproxy server

I know that with fileInput I can use browser file listing but I also need the full path of the file, and as far as I know fileInput only stores a temporary datapath
