Increase Functionality of Hands-Free Mode

As a developer, I would like to be able to detect if the user is in handsfree mode, either because they are using a device without a screen or are driving or some other hands free activity. Right now, this is limited to navigating through lists, but I would like to be able to have 2 different views: 1 for when hands free mode is on and one when it is off.

This could be solved by giving the developer access to a boolean indicating hand-free mode is on or off. Alternately, it would be nice to have something of a navigation mode that allows you to just read different data back to the user rather than it being completely focused on a list.

For example: If the user has a screen, I can just show them the contact information (ex: phone number) for a business, but if they are in hands-free mode (not able to look at a screen) I would want to read them the contact information (ex: phone number). We want to optimize the user's experience based on the way that they are interacting with Bixby, so if they can't see something, we still want to be able to convey that information.
