Live Link Face does NOT launch Take Recorder automatically if press red Record button

As you can see below, users expect to launch Take Recorder from the Live Link Face app, but it doesn't actually work.

When you're ready to record a performance, tap the red Record button in the Live Link Face app. This begins recording the performance on the iPhone, and also launches Take Recorder in the Unreal Editor to begin recording the animation data on the character in the engine.
