Find inserted emails with the Gmail API

[Rodrigo Albin]

Hi guys! Do you know any command to find (and thus be able to delete) the emails inserted with the Gmail API (Migrated)?

When viewing the message in plain text (Original Message) I can see this information that may be helpful:

Received: from 736914803254 named unknown by gmailapi.google.com with HTTPREST

Any ideas to visualize them in a massive way?

Thanks!!!
