returns a promise that resolves to an array of Document instances. It
uses the parseOffice function from the officeparser module to extract
the raw text content from the buffer. If the extracted powerpoint content is
empty, it returns an empty array. Otherwise, it creates a new
Document instance with the extracted powerpoint content and the provided
metadata, and returns it as an array.

fs/promises module in Node.js. It is used to dynamically import the
function when needed. If the import fails, it throws an error
