How to use tgt_prefix by opennmt-py v3

1

I find CTranslate2 has the target_prefiix support, which is used for autocompletion.
But how can I use tgt_prefix by opennmt_py, for example, in .yml format?
I can’t make sense to use it, like in add target_prefix decoding feature by Zenglinxiao · Pull Request #1800 · OpenNMT/OpenNMT-py · GitHub
