How should I configure Trojan Inbound (complete) in the v5 version configuration file?

[cntrump]

I can't configure the "level" value using Trojan Inbound (simplified), so I need to use Trojan Inbound (complete) for configuration

The configuration according to the official documentation doesn't work：
https://www.v2fly.org/en_US/v5/config/proxy/trojan.html#trojan-inbound-complete

I patched source:
