Send e-mail as reply using API

Hello!

Can I send an email via API as a reply to the previously received e-mail?

For example, I´d receive and email from client@exemple.com with the subject "Need your help" and tried to reply using the api as follow:

mutation {
    createInboxEmail(
        input: { 
            repo_id: [pipe_id]
            card_id: [card_id]
            subject: "Re: Need your help",
            from: "pipe[pipe_id]+[card_id]@mail.pipefy.com"
            to: "[address I'd received the email from]",
            html: "<b>just a reply test</b>",
        }
    ) {
        inbox_email {
            id,
            state
        }
    }
}

But at least on my Gmail I receive the answer in a new thread not as a reply on the previous one.

Any idea?

Thanks!
