Hi,
I'm using the firebase package to handle login to my app.
Unfortunately, half of the time, the server function sends a custom message before the js script to register the CustomMessageHandler is ran.
Is there a way to make sure the UI is "ready", i.e. all/or that piece of js, before letting the server function send that message?
Or to let shiny know the handler will come later and keep the message?
Thanks!
