Add dependency on existing AWS lambda function for nodejs

I want to update my AWS lambda function that is already deployed to AWS.

The lambda is a nodejs function

It has a javascript, package.json and package-lock.json

There is no code or steps that I can find to help with that is clear steps on AWS docs.

I looked for them but I get how to create a function.

Also to be noted I do not have the original code on git or anything. What I have is in the lambda function.

I also need to install an npm package to the function as part of updating.

Solution
