Hidden dice roll functionality

Hi, could I get a brief description of what the different dice roll visibility options do?
Show everything - default, obviously makes the whole roll visible to all players
Hide Roll/Result
Hide Dice & Roll
Hide Everything

What's the difference between "Roll/Result" and "Dice & Roll"?
Are hidden rolls always fully visible to the GM?

Correct me if I'm wrong, but I believe Hide Roll/Result only hides the actual die result like the individual die rolls and the total of the rolls. Hide Dice & Roll also hides the 1d20 or whatever the dice pool was that you actually rolled. Hide Everything also hides the description of the roll that you type in the text box.

Hidden rolls are always visible to the GM

Yup. So let's say you're rolling 2d6 with a description of "Damage roll". On it, you roll [4, 3], totaling 7.

Hide Roll/Result would show that a 2d6 "Damage roll" was rolled, but not the [4, 3] or 7 total.
Hide Dice & Roll would show a "Damage roll" was rolled.
Hide Everything would show something was rolled.

does the same apply to the DM - If I "Hide Everything" does it say Hidden Roll?

Sure does

Ah ha! Thanks, that's perfect.
