Rotation components - Yaw, roll, and pitch

When using the scripting tools in Horizon Worlds, the code blocks "Yaw of rotation", "Pitch of rotation", and "Roll of rotation" do not appear in the operations tab of the scripting code blocks panel.  These code blocks are used in assets named free spinning wheel and spring wheel, to return the yaw, pitch, and roll values in a rotation. Therefore, I know they exist but can not find them! Can anyone tell me if this is a glitched or if these code blocks are just not implemented for anyone to use yet?
