Remote storage on DropBox

...Hello everyone,
It's my first time here (and I am also new to shiny), so I would appreciate any help.
I am trying to save the uploaded files (within my app) to a remote dropBox. I have been trying to implement what I learned here: [https://shiny.rstudio.com/articles/persistent-data-storage.html](Permanent Storage) but so far no luck.

Here it's a snippet of my code:

Server:

t#### To upload file and generate a Table ####
    data <- reactive({
      req(input$file)

      ext <- tools::file_ext(input$file$name)
      switch(ext,
             csv = vroom::vroom(input$file$datapath, delim = ","),
             tsv = vroom::vroom(input$file$datapath, delim = "\t"),
             xlsx = read_excel(input$file$datapath, sheet = 1),
             validate("Invalid file; Please upload a .csv, .tsv or excel file")
      )
    })

    # When the Submit button is clicked, save the form data
    observeEvent(input$file, {
      saveData(data())
    })
    
  
    output$table <- renderDataTable({
      input$file
      #data()
      
      # DropBox
      loadData()
  })
    

I would greatly appreciate any help as I am trying to teach myself the elements and features of shinydashboard.
