If I begin a dialog with a user where in the middle that user is sent a link that they are meant to open, how can I resume the conversation with the user after they have closed the webpage (which I control) the link lead to?
They way I implemented this myself, without using BotBuilder for Node.js v3, was that the link I send to the user has the chatId information associated with it, so when the user later closes the webpage the link leads to, the webpage sends a call to my chat server saying its time to resume the conversation with the specific chatId.
With BotBuilder for Node.js its unclear how I could get it to send a one off message for a specific chatId on a specific channel or begin a new dialog with a user that is triggered by a website or source other than the direct chat recipient. Can someone please give me guidance on this?
