Animatable deformation on static mesh

Using this instruction on deformation graphs (Deformer Graph in Unreal Engine | Unreal Engine 5.5 Documentation | Epic Developer Community), I’m trying to apply a deformation onto a primitive object.
After creating the Deformer Graph, it mentions needing to enable the Mesh Deformer property in the Details panel of the object, but I don’t see a Mesh Deformer property. What am I doing wrong?
