I would like to trigger a function on the callback of the initial application initialization.
Currently the documentation suggests using the onAuthStateChanged and this works fine after the initial load.
When the page first loads I would like to display a spier to represent checking to see if the user is already authenticated.
The thing is, onAuthStateChanged will only execute if a user is found and logged in, I need to be notified if no user was found.
Can this be done?
