Facebook Marketplace-Discord Link Copier per Johninatoooor

Adds a new button inline with Facebook Marketplace's buttons on a listing. This button lets you click on it to copy the url to your clipboard but in a markdown style Discord message. The purpose of this is to create a faux-embed because Facebook does not embed their links in Discord at all. So the message it generates for you when you click the button will contain the marketplace listing URL, trimmed of all the excess, and an embedded image/video of the current media you are viewing on the listing page.

Note: This extension was partially created with the use of AI. This is not intended to be a super polished production extension - just a test to learn how to create new things.
