Build a GitHub Actions application which posts documentation files on GitHub to StackOverflow articles using API

Build an application using GitHub Actions based on NodeJS (or Python, but NodeJS is preferred) which posts the Markdown files hosted on a GitHub repository to Stackoverflow articles. Since Stackoverflow offers full REST API (https://api.stackexchange.com/docs) for articles, we'd like to automate the publishing of finished documentation articles (available as Markdown files) from the GitHub repo to Stackoverflow articles as soon as the Pull Request for the document article is reviewed and merged to the main branch of the GitHub repo.
