Im trying to use xcrun altool to get my app notarised, what is --asc-provider parameter?

I'm trying to notarise my app from apple using xcrun altool, the documentation shows the following : xcrun altool --notarize-app --primary-bundle-id "com.example.ote.zip" --username "AC_USERNAME" --password "@keychain:AC_PASSWORD" --asc-provider \ --file OvernightTextEditor_11.6.8.zip but I couldn't find the parameter to provide to the --asc-provider can any one let me know what it is and where to search for that parameter. All other parameters I have found and fine. Help me out I'm new to mac.
