Hi, I'm trying to decide on which plan to go for. I just want to make sure that M is 4 million in terms of characters that would be index as a library for the bottom to answer from.

Secondly, regarding my previous question, especially question number 2, I was trying to see if it would be possible to devise a way so that only paying customers could use the WhatsApp AI chatbot. I pose this question on your website chat but and he gave me the following answer. Are you seen the screenshot: https://prnt.sc/PNdUjILl-wT3
The answer the chat gave me is that correct? If I sign up, would you be able to give me some guidance on this? I would sign up to possibly Tier 3 or higher. However, that element of being able to only allow existing customers to use the WhatsApp chat button is important for me. Thanks. Sye
