Export glb from sandbox

Hi folks I have my animated Trex looking and moving great in sandbox but now I need to export it to hand over to a developer but I cant export the animation as part of the scene export.

Why not?

The support for skeleton and morph is not yet available in the gltf serializer : GLTF serializer: Add bones and morph target animation support · Issue #5100 · BabylonJS/Babylon.js · GitHub
