Is there an analogue of ngrok with UDP support?

Question

Computer networks

I have a Node.js server to which I can connect through the game. The game supports connection only via UDP.

The hosting is on Heroku and tunneling is required so that it can be connected from the outside world via UDP.

The first idea that came to mind was to use the ngrok js module, but as it turned out, ngrok itself still does not support UDP.

Are there any free alternatives to ngrok with UDP support? Perhaps there are other solutions to this problem?
