I would like to know that we are having a lead generation campaign running on Facebook but few of the times our staff isn't available to answer the query on Facebook messenger, so based on that short-coming I am thinking to devise a mechanism that "If within 1 hour of user's message no one replies to him then an automated BOT message should get sent to him."
Please don't deprecate this question as it is based entirely on knowledge. And if perhaps someone has hints or links on how to achieve this thing then I will really appreciate it.
Thanks.
