Webdav client propfind

I am trying to write a webdav javascript client, but am running into problems right out of the gate.

First I want to get the files in the / directory (main directory).

PROPFIND 401 unauthorized

From Chrome developer tools/network/headers

Note: I masked out my real username and password and url.

Is this the proper way to do a PROPFIND on the top directory?

Thanx

If it helps, here is webdav-fs. It is built with node.js

I need it to work in a browser, it will be an extension. So Node is out. I am basing this on another github library. I am thinking there is something Nextcloud-ish I am doing wrong because the library I am using I am extending to have a username and password with it.
