title: How do I actually add Filesystem Access API to javascript?
body: <p>I've found this <a href="https://developer.mozilla.org/en-US/docs/Web/API/File_System_Access_API" rel="nofollow noreferrer">https://developer.mozilla.org/en-US/docs/Web/API/File_System_Access_API</a> to allow javascript to access the local file system. I feel really dumb, but I can't find anywhere that talks about how to actually add the api. I would really appreciate some help on just getting the first step.</p>
