URL to access an embedded folder

I want to create an iOS shortcut that opens the NextCloud app to a folder within a folder.
I first tried this (no embedde folder):
nextcloud://open-file?user=xyz&link=https://cloud.xyz&path=Uploaded
and it worked fine. But there is a folder within the Uploaded directory that I want to access, so I tried this:
nextcloud://open-file?user=xyz&link=https://cloud.xyz&path=Uploaded/Folderof Interest and it opens to the Uploaded level, not to the directory Folderof Interest. Do I have the wrong syntax or is this not supported?

I can not test it. But in the directory sharing option you can copy internal link to clipboard for cut and paste. The url for a directory or subdirectory is e.g. https://cloud.server.tld/f/123456. Copy your internal link and maybe you can use it in any way.
