XML asset path

I am trying to read some data from an XML file and for some reason I cannot see the file in the Content Browser. The file is definitely on the disk (with the .xml extension) but for some reason it doesn’t appear in the Content Browser in the Editor.

I am not a 100% sure I am meant to see the file in the Content Browser because the extension .xml is not listed in the extensions Unreal can import. If not, what is the path that I am supposed to pass to FXmlFile? When I want to load an asset I usually get its path by selecting “Copy Reference” in the Content Browser.
