Secret or Hidden Variable Type

We would like to see a new variable type, secret or hidden, similar to Postman. This variable would be useful inside LE. A use case we have is internal REST calls. For OAuth 2.0 the Body requires a client secret and/or API Key. Currently there is no way to hide these from developers.

In addition the Authentication section of the REST action does not allow RPA Central as an option if using Basic Authentication.
