Is It possible to send marketing messages/ updates to users on WhatsApp?
The main focus is to automate the process.

If any user is likely to show interest in chatBot on the website, we intend to send relevant promotions to the customer via WhatsApp.

I have created a subdomain and mapped the server's external IP address to the DNS https://domain.com
In my .env,

NEXTAUTH_URL = https://domain.com
NEXT_PUBLIC_VIEWER_URL = https://domain.com

Currently, both the URLs in env are the same. What should be the NEXT_PUBLIC_VIEWER_URL?

if I keep the NEXT_PUBLIC_VIEWER_URL = https://bot.domain.com the server is not able to make a connection

should I create a new subdomain and map it with NEXT_PUBLIC_VIEWER_URL?

I have self hosted the Typebot in my own server. Tried to test and publish a chatBot from the template but it returmns error 404.

Or even after self-hosting, there are any limitations in the number of chats/month?
