c# - Xamarin KeyStore is lost

Question

I have formatted my development machine without due to hardware failure and haven't backup my keystore files now I need to update my app in google play but it refuse because of signing difference. I will try : "Upgrade app signing key" but what is the better choice in my case ? I have chosen "I need to use the same key for multiple apps, or a pre-installed version of this app" in this option they ask to download a PEPK tool and run this command

$ java -jar pepk.jar 
--keystore=foo.keystore 
--alias=foo 
--output=output.zip  
--signing-keystore=uploadkey.keystore 
--signing-key-alias=upload-key-alias 
--encryptionkey=encryptionkey

My problem is that visual studio creates only one keystore according to https://docs.microsoft.com/en-us/xamarin/android/deploy-test/signing/?tabs=windows and in the command line two keystores are required so where to find them??

any help will be appreciated
