I can see from this, that a bot can send a message in chat, and if supplied a thread ID that does not exist, will start a new thread and post there. I am wondering if there is a way, given the current REST API or any other compatible with Hangouts, to send a message to a room at a given time of day, rather than when the bot is called or interacted with.
I am working in NodeJS, deploying my project in the GCP.
My apologies for the ambiguity of my question, I am trying to wrap my mind around the GCP environment.
