mesh export uv texture help

Need some help on how to get uv texture. (uv1,uv2,uv) But I can’t get it working. Trying to understand how the .obj export work. But I don’t get it. Need some help on it.

Just an example a simple model and uv is created from user. But I can’t find the uv texture. There are two of them. uv_textures and tessface_uv_textures that is not found. But there is uv model in there.
