Can i use wss://url in config file of an argo tunnel

Can I use wss://url in the config file of an argo tunnel?

Example:

If the request comes to abc.xyz.com then it should send it to the service: was://websocketurl.net

According to documentation, no:

Okay thanks, and is there any workaround for integrating argo tunnel with the application which uses websocket wss://
