I'm fairly new to programming and am trying to implement Google authentication in my Shiny app using the googleAuthR package - I've been trying to run the sample code listed for the googleSignIn module here.
I've set up a Google client ID following the steps here but attempting to sign in using it results in the popup saying "Just a moment..." before disappearing without signing the user in. I believe this might be an issue with my setup of the Google client ID as replacing my client ID with the one provided in this working example works and allows login. Is there something I've missed in setting up the API client?
