I have done some scripting on google scripts to create messages and trigger those according to certain conditions. Also this script is linked with an external API tool that my team has developed which automates a few clicks which are required to send the message.
Check this thread for more information.
Though this wasn’t sufficient to make a running tool, we did learn a lot from this. If you are interested in something of this sort for any of your apps, we could connect on private chat!
