How to handles bounces with gsuite and outlook SMTP?

Your software
My Mautic version is: 3.02
My PHP version is:7.4

Your problem
I’m using Gsuite SMTP to send emails, but the documentation says something quite cryptic that this cant’ work over here:

“Some email services overwrite the return-path header with that of the account’s email (Gmail, Amazon SES). In these cases, IMAP bounce monitoring will not work.”

The question pertains to what should I input into the whole “Monitored Inbox Settings” section.

I need to send emails via Gsuite SMTP, so what should I input into “Monitored Inbox Settings” for Default Mailbox , Bounces and Unsubscribe requests ?
