Part of insightsengineering/teal#1370

Working Example

library(ggplot2)
interactive_decorator <- teal_transform_module(
  ui = function(id) {
    ns <- NS(id)

      reactive({
        req(data())

               {
                 plot <- plot +
                   xlab(my_title)
               },
               my_title = input$x_axis_title

Do we want to have an error showing in the decorator's UI?

Using the example without X and Y

We might want to add a custom wrapper on srv_teal_transform_data that will return the original data if that has an error.
