glTF does not implicitly support animating a visible/invisible feature in the way you would like.
But the visible/invisible feature can be simulated using the SCALE.
Let's say you have 30 meshes, and you only want a single mesh to be visible at a given time.
What you would do is to set the initial scale of all the meshes to ZERO, that makes the meshes effectively invisible.
then you create a STEP animation for every mesh, where you animate the scale of all the 30 meshes, and you set the SCALE of the given mesh to zero, except for the frame you want to show.

Thank you for your sooner reply.
I also thought that I couldn't help but using SCALE animation.
Because I'm not goot at .gltf format as I said in question, I had wanted to ask you, the .gltf expert, if I could change the visibility of mesh in the gltf animation or not.
I will use SCALE animation as you said.
