How to define MQTT User Properties in an AsyncAPI document?

[aysancag]

Hi,

I am working on defining a spec for a service that operate over MQTT using AsyncAPI. We defined messages that use MQTT v5 user properties described here: https://www.hivemq.com/blog/mqtt5-essentials-part6-user-properties/

However, we weren't able to find how to correctly define the User Properties in the AsyncAPI specification. We defined them in Headers for now, but I am not sure if that is the correct approach. Is there way to define them currently?

I found these related issues:
