How to create a destructible mesh without Apex?

I’m developing mobile project and I need breakable glass in scene. But yesterday I found out that mobile doesn’t support Apex, so I tried to break glass in blender and export it as fbx. I’ve set Physics Simulation to true and unchecked Start Awake, then set derbis cells collision to 26D and set collision preset to collide only with pawn. But in game every time I touch it it goes flying out in high speed (parts are not colliding with each others). So it’s not working too
Animation is not a variant because character can hit glass with different velocities
Is there any tutorial about destructibles without Apex?
