The short answer to this question is: You can't.
The long answer is still no but, contains an explanation on why you can't. This is not lack of functionality, at this moment of time it is a conscious decision we've made in order to make feedback as organic it can be.
We want users of Conflux to digest the feedback from their users and come up with Ideas to address the feedback. If we were to make feedback public you might run into moderation issues, or have situations where users are biased by others.
Some people also don't like to complain in public (while others might seem to love it). While when the user gets the guarantee that their feedback will only be read by you, the company representative, they might go all out.
