Is there a global busy indicator for R shiny/dashboard applications. I do not want to set an indicator to each chunk everytime like the example given below: https://mastering-shiny.org/action-feedback.html?q=progr#progress-bars
But I am looking for something that I want to set once and it will simple indicate busy notifications whenever shiny server is making a somewhat long calculations (10/30 seconds).
I think this should be a default behaviour of shiny but I could not see anywhere something like this.
I saw this library but did not work: https://cran.r-project.org/web/packages/shinybusy/vignettes/shinybusy-usage.html
