Join the Data coming from different sources into one Single Object to push to MongoDB

Good Morning,

I have a array of numbers coming from a device.
I have an array of Objects coming from a HTTP request as a response and I want to merge these two data into a single object and Append the timestamp with it to push it to a Mongo database in a different collection.

How can this be accomplished?

You can use a Join node set to generate key/value pairs to get a single message containing both sets of data. I think there is an example in the node red cookbook but can't look it up at the moment.
