SDL3 GPU: API Interoperability

Is it possible for SDL3 GPU to share a logical device from another context, for example from Unity? Doesn’t look like it’s possible from the documentation / accepted parameters, but just wanted to confirm.

Related, does it support accessing a shared texture handle created from a graphics API (e.g. ID3D12Device::CreateSharedHandle (d3d12.h) - Win32 apps | Microsoft Learn)?

Thanks!
