I'm trying to figure out a way to act upon a private chat message that is sent (either from another user or bot) and NOT read. For example: how can I make it where whenever a message is sent and not read in 10 minutes, it gets sent again or after a certain time period our system sends them an SMS instead? I know they came out with priority notifications which pings every 2 minutes until it is read up to 20 minutes but I need a "fail safe" that if a message is not read after a specific time period that we do something about it (either send it again or send it to another person). Can I do this through the admin center or graph API? Any help would be appreciated, thanks!
