Seperate Labels.txt file for TensorFlow Lite Object Detection Android App

I was wondering whether anyone had any idea of how to use a tflite model that has a seperate Labels.txt file rather than inbuilt metadata from the model?

I’m having a look at the TensorFlow Lite Object Detection Android Demo app with realtime video feed listed here:

Object Detection App

I see this a lot with classification apps such as the Pose Estimation Android Demo and the Flower Classification Android Demo, just wondering whether this is a big step for Object Detection apps and whether anyone has any examples of it implemented? Better yet, any hints on how to do this in the Object Detection app?

Pose Estimation App for reference.
