Changing the initial shinyapps "Please wait" message

Is there a way to change the initial "Please wait" message when an app starts upp on shinyapps? I'd simply want to change the words, not the loading bars. Does anyone know if this is even possible? I can't seem to find anything about it online nor in the documentation for shinyOptions()

To be clear I'm not looking for packages such as shinyBusy or waiter as I am referring to the sole startup message of shinyapps.io while the packages and such are being loaded :slight_smile:
