text2motion/blender-integration ? reverse-engineered prompt

Build me a Blender add on that lets me type a text prompt and send it to the Text2Motion service to generate a 3D animation for a Mixamo rigged character.

I want it to work inside Blender 4.2, with a simple panel where I can paste my API key, enter a prompt, and click a button to generate the motion on the selected character. It should support GLB imports for the character model, and it would be great if the animation can be applied with or without root motion. Please also let me choose whether the animation length is automatic or set a custom duration in seconds.

Make the experience feel clean and easy for someone who just wants to test it quickly with the included sample model. If you need to check any current Blender extension docs or API details, go ahead and look them up online.
