I deeply apologize about the n00bie request but I cannot find anywhere on how to acquire the history array to determine last changed state of a person within a function. I have figured out how to use the HA websocket api-get-history as a node but I need to do the same within a function for multiple persons/devices. Can someone guide me on how to do this?

```auto
