Revoke access to a Google Drive File having an email

Hello!

I’m trying to revoke access to a file when a Patreon cancels.

I have a trigger (Patreon cancelation) - which outputs an email.

Then, I’m doing an API Call to Drive, to list all permissions to the file

This correctly brings all permissions, but with an ID, and no email

Is there a way to get the ID for the permissions, so I can then map this ID, and revoke this specific permission?

I saw this french article posted in the community, and with the same API call (except they use v2 instead of v3) it apparently brings the email for each permission. I tried it and still nothing.

Any ideas?
