Subscribe to watch later and favs

```
I just found this Tool and it works fine with channels, but is it possible to 
generate feeds for my watch later and favs? 

I tried favs first, but I get a 500 error when I paste the link in the browser. 

Then I tried watch later, but there is no playlist id in the URL.
