Quickbooks migration app doesn't appear to be doing anything

I have followed the directions here to migrate my data from Quickbooks Online to my on-premise Akaunting instance: https://akaunting.com/hc/docs/getting-started/migrating-to-akaunting/quickbooks/#migrating-as-an-akaunting-on-premise-user

After saving the client id and secret, I click the auth button and authorized the app for the correct company in Quickbooks live. After that, Quickbooks redirects me to their app marketplace and nothing else appears to happen in my Akaunting instance.

Is there a missing step or some where I can check to see the status of the migration?
