receiving emails google cloud

Hello,
I need to configure google cloud to receive the emails in the cyber panel, is there any documentation for this?

the submissions are already secured by an external smtp, now I need to set up the receipts in the cyberpanel email boxes.

For now, we only have one guide related to Google Cloud and Emails → Setup External SMTP on Google Cloud Platform (GCP) - #2 - Blog Posts - CyberPanel Community
