No, the expectation is that a novice may not have any idea how to chat, how to parse the idea of being invited to something, or know that they even may need help in the first place (this one is especially true).
While I've not been very invite-happy myself, helping people who are invited, even if it's to help them out of it (there's some irony there...) is still how it should work. We don't need people who do need help hitting No on their invites. Nor do we want to pester them with consistent invite prompts.
