I'm sorry but as long as we're not releasing any updates it doesn't make sense to put more time into this atm.
The next update will fix API download and thus also watermark-free download.
We'll go with the solution we got now until it doesn't work anymore.
Your 2nd link seems to link an archive containing all kinds of tools- and helper-tools for downloading tiktok items.
If you can't wait for it, you can grab our source code at any time and test developer builds to provide early feedback:
