Cicerone does not work in shinydashboard

I build shinydashboard that has 6 tabItem. I want to use cicerone package to guide first tibeItem. I write following code:

library(shiny)
library(shinydashvoard)

guide <- Cicerone$
    new(id = "homeGuide")$ 
    step(
      el = "macro_upload",
      title = "Upload Macro Data",
      description = "This is where you upload macro data."
    )$
    step(
      el = "mcr_df",
      title = "Sample of Data",
      description = "Here you can see sample of your data"
    )$
    step(
      "adf_test",
      "ADF Test result",
      "Hare you can see result of ADF test, for choosen variable"
    )$
    step(
      el = "slider-wrapper",
      title = "choose lag",
      description= "Choose lag in ADF test"
    )
ui <- dashboardPage(
  dashboardHeader(title = "PD Model"),
  dashboardSidebar(
    sidebarMenu(
      menuItem("Stationary test", tabName = "stationary", icon = icon("chart-line")),
      menuItem("Import Data", tabName = "import", icon = icon("server")),
      menuItem("Explore Data", tabName = "explore", icon = icon("cogs")),
      menuItem("Visualise Data", tabName = "visualisation", icon = icon("bar-chart")),
      menuItem("Model development", tabName = "development", icon = icon("layer-group")),
      menuItem("Validation", tabName = "validation", icon = icon("tools"))
    )
  ),
  dashboardBody(
    use_cicerone(),
    tags$head(
      tags$style(HTML('
      .main-header .logo {
        font-family: "Georgia", Times, "Times New Roman", serif;
        font-weight: bold;
        font-size: 24px;
      }
    '))),
    tabItems(
      ####### Zero Tab ####
      tabItem(tabName = "stationary",
              box(width = 5, height = 400,

                            buttonLabel = "Upload...",
                            accept = c('csv','tsv')),
                  actionButton(inputId = "tutorial", label = "Tutorial"),
                  dataTableOutput("mcr_df", width = '100%')
              ),
              box(width = 6,
                  height = 400,

                      ) 
                    ),
                    column(

I am unfamiliar with cicerone but you can start with this:

thank you for answering. Indeed, I had loaded this package, but I don't show this code here.
