I need to provide some permissions to an user in order to reply to the reviews on Google Workspace Marketplace, however when following a "Reply to user reviews" documentation I found, it says that I need to provide the Project Editor access to this user just for her to be able to reply to these reviews. As you could imagine, I can't do that otherwise this user will have an excess of unnecessary permissions, which could be dangerous.
What I need
Is there any way that I can provide just the necessary permissions for any user to reply to reviews? Is there any way to create a Custom Role on GCP IAM? If so, what are the necessary granular permission should I give?
Thanks in advance
