Update NavMesh Link at runtime

Question

Hi,
I want to bake NavMesh at runtime.
When I use NavMeshBuilder.BuildNavMesh, navmesh is generated with links, but the impact on performance is quite heavy.
If I use NavMeshBuilder.UpdateNavMeshDataAsync, navMesh is generated, but WITHOUT links, even if all my NaMeshBuilderSources are GenerateLinks=true, and even with generateLinksByDefault=true in NavMeshBuilder.CollectSources.
Do you know how to make UpdateNavMeshDataAsync generate links?
Thanks
