How to collapse sidebarpanel in a brilliant app?

Question

I have a brilliant app with mainPanel and sidebarPanel inside tabPanel in navbarPage. I need an option to hide the sidebarPanel like this: Hide the default sidebar in shinydashboard and https://github.com/daattali/shinyjs/issues/43 .

The actionButton element must control if the sidebarPanel is displayed or reset.

This is the code:

library(shiny)
library(shinyjs)

ui <- fluidPage(
  navbarPage("",
             tabPanel("tab",
                      sidebarPanel(
                        useShinyjs()
                      ),

                      mainPanel(actionButton("showSidebar", "Show sidebar"),
                                actionButton("hideSidebar", "Hide sidebar")
                      )
             )
  )
)

server <-function(input, output, session) {
  observeEvent(input$showSidebar, {
    shinyjs::removeClass(selector = "body", class = "sidebarPanel-collapse")
  })
  observeEvent(input$hideSidebar, {
    shinyjs::addClass(selector = "body", class = "sidebarPanel-collapse")
  })
}

shinyApp(ui, server)

Hope someone can help :)
