Send an email from Google Security Operations SOAR and log the response

This can be done either by running a manual action or in a playbook, by selecting the Send Email and Wait action.
This action will send an email using SMTP, and then query the mailbox periodically for a response (looking for a unique ID to identify the correspondence). Once received, the action will fetch it into the platform.
The response can be seen on the case wall and used as an input for other actions in the playbook.
