Try this:
./anttp -w <your 64 char hex code here> -a <your other 64 char hex code here>
There is a long or short format for the argument. You don’t need both. Blame the clap library for not making that clear! 
I actually created a blog page to test the above out this morning: https://anttp.antsnest.site/gimim/blog/07045bac77fd0474ac2c2d6040056739fa350cd6abc28eee1e5040fed726dad2/article/setup-anttp-for-writing-data.md#article
The publish page is a bit finicky, though. You can only use it in proxy mode atm. It needs some love! Just been too busy with anttp and life!
Glad you got ant CLI working with it too though! That shows the separation of data and app nicely!
