Calendar ID+"_add" not possible anymore after toastui > 0.2.1

[trafficonese]

I am aware that the JS-library has changed, but I couldnt find any solution to this. I need to create custom Popups to create additional calendar entries. This example app used to work with v0.2.1 and I dont know how to migrate it..

Those issues seem related: https://github.com/dreamRs/toastui/issues/8 https://github.com/dreamRs/toastui/issues/36

library(shiny)
library(toastui)

ui <- fluidPage(
  calendarOutput("calendar")
)

server <- function(input, output, session) {
  output$calendar <- renderCalendar({
    calendar(NULL, view = "month",
             navigation = TRUE,taskView = F, height = 500,
             useCreationPopup = FALSE, isReadOnly = FALSE)
  })
  
  observeEvent(input$calendar_add, {
    print("input$calendar_id_click")
    inp <- input$calendar_id_click
    removeUI("#calendradd")
    shiny::insertUI(selector = "#calendar", where = "beforeBegin",
                    ui = selectInput("asd123", label = "Select", choices = 1:9))
  })
}

shinyApp(ui, server)
