Hide that role from members who don't have a role

I wanted to create a channel and role that I don't want members who don't have a role to know about, but there doesn't seem to be a way to hide the role.
The feature I would like to see is simply to make sure that only the role and the members who have the ability to manage it are aware of its existence.
I hope that members who don't meet the requirements will not be able to see the role list of the member with the role, and they won't be able to send comments.
