Beginner Level 2

I had google authenticator installed and couple of 2-factor accounts configured in it. I did not use Google Authenticator for a while and it got dissappeared from phone. When checked i found Google authenticator got zipped by Samsung's "Zipped apps". I unzipped Google Authenticator now however the accounts configured within the Google Authenticator app are missing. The Google authenticator open as a fresh installation.  Can you please help, if there is a way for retrieving the configured accounts (ie unzip or retrieve Google authenticator configurations as well)
