some question about using Google Cloud Document OCR Connected System

Hi there,

I am new to Google Cloud Document OCR Connected System in Appian. I have created the connected system. just want to use it in the integration. but I dont know what should be put in the two circled fields in attached pic.

Do I need to go to google to create a "Google Storage"? or Appian provide these storage? if I need to create myself, anyone can provide information how to do it? and the credential use to create google storage need to match the credential used to create the connected system?

regards,
