Need help on how to configure it as a first time user

[yoonjigh19]

Hi, here's what I've done so far:

1. Downloaded Node.js for Windows and made sure it's installed using the CMD check, I think the PATH is already set as well.
2. Installed Visual Studio and the node.js extension pack
3. Downloaded the file node-twitter-api-v2.zip here in GitHub and extracted it as a folder
4. I opened VS and navigate to File > Open Folder > node-twitter-api-v2 (folder)
5. It prompts me if I trust the author, I click YES.
6. Now I'm inside the VS with node-twitter-api-v2 opened, I run the script: npm i twitter-api-v2
7. It downloaded the package successfully.

Now I want to run it but I'm not sure how, I've read the DOCS and the QUICK SAMPLE ON HOW TO USE but I can't seem to figure out where to paste the script and how to run it.

So what I did is:
Trial1: I created a new file called mytest.js and inserted the script from "QUICK SAMPLE ON HOW TO USE" and run it in the terminal with the command: node run mytest

It didn't work...and threw an error:
Error: Cannot find modole 'C:\User\*\run'
code: 'MODULE_NOT_FOUND
requireStack: []

Can somebody give me some directions as I'm not that of an advanced user but I do have a little background on javascript and jquery, once I pick up on how it's working, I can modify/change and explore on it afterwards.

Will appreciate the help and is it okay if you guys can tone down some of the technical words lol since I'm quite slow.

NOTES: I signed up as a Dev in Twitter with an Essential access, I think it's restricted for v2 only, right?

I'd like to at least make the following things work:

Here are my goals on the list of things I want to make it work in VS:
-Tweet something on my own timeline, just a simple tweet.
-Stream real-time on a specific users's tweet post with the ability to set how many tweets it fetches before the stream closes as I do not want to hit the rate limit.
-When somebody sends me a DM, it will automatically reply with my pre-set message.

That's all.

THANKS!
