How it works

customer requests a chat from your website
Live Helper Chat will send a message into a specified channel with a button to accept this chat request
One operator will click the button to accept the request (the message now disappears)
Live Helper Chat will now create a new channel for this chat and invites the operator
All messages from the customer will appear in this new channel and all messages from the operator will apear to the customer on your website, even files can be made aviable for the customer or for the operator
(optional) The Channel will be deleted after a given amount of time after the chat has been completed. All chats are still aviable in Live Helper Chat Backoffice for the manager

Install instructions for Mattermost part

I would suggest creating a new team dedicated just for your customers.
Create a user under which Live Helper Chat will be sending messages, creating channels and webhooks. It should be a user with admin permissions.
Create one channel in this group where live chat request will appear.
Invite few operators to this group.
