I emailed support a few days ago about this “whitelist” and received
“Hello,
Thank you for reaching out. We are not currently whitelisting bots for whispers.
One thing we strongly recommend doing for Chat Bots, is to enable 2FA for the account. Since the accounts are not “logged into” on a regular basis, it is always good to take precautions to ensure that the account is not compromised when you’re not checking on it regularly.
Please feel free to reach out if you have further questions or issues with the bot!”
