当闪亮的应用程序第一次启动时显示一个按钮，这将导致 tabItems 内容

如何解决当闪亮的应用程序第一次启动时显示一个按钮，这将导致 tabItems 内容

我在下面有包含 tabItems 的 shiny 应用程序。我希望在第一次启动应用程序时显示一个 actionbutton，它将超出 tabItems 内容。然后当我按下它时，我将被移动到 Consent tabItem。这个按钮从那以后就没有用了，它应该消失，因为将显示 tabItems 的内容。

library(shiny)
library(shinydashboard)
library(shinydashboardplus)
library(shinyjs)

mytitle <- paste0("")
dbHeader <- dashboardHeaderPlus(
  titleWidth = "0px",tags$li(a(
    div(style="display: inline;margin-top:-35px; padding: 0px 90px 0px 1250px ;font-size: 44px ;color:#001641;font-family:Chronicle display Light; width: 500px;",HTML(mytitle)),div(style="display: inline;padding: 0px 0px 0px 0px;vertical-align:top; width: 150px;",actionButton("conse","Consent",style=" background-color: #faf0e6; border-color: #faf0e6")),),class = "dropdown")
  
  
)

shinyApp(
  ui = dashboardPagePlus(
    header = dbHeader,sidebar = dashboardSidebar(width = "0px",sidebarMenu(id = "sidebar",# id important for updateTabItems
                                           menuItem("Consent",tabName = "conse",icon = icon("line-chart"))
                               )           ),body = dashboardBody(
      tags$head(tags$style(HTML('
  
    '))),useShinyjs(),tags$script(HTML("$('body').addClass('fixed');")),tags$head(tags$style(".skin-blue .main-header .logo { padding: 0px;}")),actionButton("button","Get started",style='padding:4px; font-size:140%'),tabItems(
        tabItem("conse",textInput("pos",label = ("Position"),value = "")

                )
        

      )
      
    )
    
  ),server<-shinyServer(function(input,output,session) { 
    hide(selector = "body > div > header > nav > a")
    
    
    observeEvent(input$button,{
      
        updateTabItems(session,"sidebar",selected = "conse")
      
      
    })
    
  }
  )
)

    '))),useShinyjs(),tags$script(HTML("$('body').addClass('fixed');")),tags$head(tags$style(".skin-blue .main-header .logo { padding: 0px;}")),actionButton("button","Get started",style='padding:4px; font-size:140%'),tabItems(
        tabItem("conse",textInput("pos",label = ("Position"),value = "") )
      )

    )

  ),server<-shinyServer(function(input,output,session) {
    hide(selector = "body > div > header > nav > a")
    shinyjs::hide("conse")
    shinyjs::hide("pos")

    observeEvent(input$button,{
      shinyjs::show("conse")
      shinyjs::show("pos")
      updateTabItems(session,"sidebar",selected = "conse")
      shinyjs::hide("button")

    })

  }
