Hello, You need KHR_animation_pointer extension to perform what you want. This extension is managed, starting Blender 4.2 beta

And then you have to enable the feature at export (available for Scene & NLA Track animation mode)

PS: There is still an issue when your animation starts with alpha value 1.0 Fix in progress
