we want our admin login in whmcs and can chat from there
like inside whmcs there is some page where our agent can chat with our clients, and they don't have to separately login in tawk to.
This must be done via some API connection rather than signin by giving user/pass. We want our admins can only chat via whmcs, and no user/pass required to login into it. it always connect via API.
Also they only have access to receive chats and chat with customer they do not have access to change or add predefined replies.
