How to write a lane for downloading metadata and screenshots from app store for multiple brand variants in ios?

Question

I get stuck at the 6 digit verification code when doing this:

for it in whitelabels do

sh "fastlane deliver download_metadata --app_identifier com.test.test --metadata_path ./Metadata"

end

And when doing this,

app_store_connect_api_key(
  key_id: 'test',
  issuer_id: 'test',
  key_filepath: './test.p8',
  duration: 1200, # optional
  in_house: false, # optional but may be required if using match/sigh
)

for i in variants do

sh "fastlane deliver download_metadata(api_key: #{lane_context[SharedValues::APP_STORE_CONNECT_API_KEY]}, app_identifier: 'com.test.test')"
sh "fastlane deliver download_screenshots(api_key: #{lane_context[SharedValues::APP_STORE_CONNECT_API_KEY]}, app_identifier: 'com.test.test')"

end

Upon executing it, I get an Unauthorized error.

Can anyone let me know if there is a way to download metadata for multiple variants from app store in ios in one go?

Any help would be appreciated. Thanks
