Hi @bachgarash, thanks for your contribution! While I haven't yet looked deeply into the code I noticed that you are lacking docs for this PR. Some docs will be generated by running make generate-component-docs (I suggest you start by doing this) and others need to be manually added.

The most recent example I can remember of a new source PR is 23449. You can take a look at that PR and take a look under the files added under website for a template (added only not modified).

Also please include a Vector config and a test plan to make it easier for us to review your PR. Thanks!
