Hi,
We’ve started using your tool for our clients and need a few clarifications:

1. Is the WhatsApp number during setup meant to be ours (the account owner) or the number used on the client's site?
2. How can we add and manage multiple domains in one account on tochat.be?
3. When we set the language for a domain, the dashboard language also changes. How can we keep the dashboard in English?
4. Your YouTube channel has great content—we’d love to learn more. After registering and adding the code to the site, could you share the best YouTube links for configuring and managing basic features?
5. Can we use one WhatsApp Business number to manage multiple sites?

Thanks
