Animation and Mesh are not working in .gltb export

Hello Blender Community.
I am new in exporting with gltf, but what I had found in YT and Google is not allowing me to export properly my project.

Here is the link for the source file: https://drive.google.com/file/d/1u8eeSslfIv3-iT2hAyUb0BlacgYbCEIe/view?usp=share_link

This are the export setting Im using:

The result of the export is really bugged:

The animation is linked with the armature, but the mesh is not attached to it some how.
There is another poblem like the duplicated helmet that i dont have idea what is happening there.

I know I am doing something wrong,and it would really, really help to show me the mistakes I ve made so i can satrt fixing them.

Thanks very much for this space.
Tom
