👩‍💻 Reviewer Notes

This is was a little fiddly as the api-extractor does not export export paths, additionally the way the api-documentor works assumes a single entry path. This is why if any additions need to be made to expose more export paths, we will need to edit 3 different files to get the documentation to show up on the documentation website.
