How do I use Renderdoc to debug fragment shader compiled by DXC at hlsl level?

[CretaceousConstructo]

I read through the documentation of Renderdoc:

On Vulkan RenderDoc supports source-level debugging via the NonSemantic.Shader.DebugInfo.100 extended instruction set. This information can be generated by glslang using -gVS to specify debug information, and by dxc using -fspv-debug=vulkan-with-source. In both cases this will embed the necessary debug information in the SPIR-V blob to debug at source level.

So I added the following options to my dxc compiler:

 std::vector<LPCWSTR> arguments;
    //COMPILATION ARGUMENTS
    arguments.push_back(L"-spirv");
    arguments.push_back(L"-fspv-target-env=vulkan1.3");
    arguments.push_back(L"-fspv-debug=vulkan-with-source");       //Include source code info
    //put your shader name here
    arguments.push_back(wstr.data());
    arguments.push_back(DXC_ARG_WARNINGS_ARE_ERRORS);             //-WX
    arguments.push_back(DXC_ARG_DEBUG);                           //-Zi
    arguments.push_back(DXC_ARG_PACK_MATRIX_COLUMN_MAJOR);        //-Zpc
    arguments.push_back(DXC_ARG_SKIP_OPTIMIZATIONS);        //
    arguments.push_back(L"-HV");        //hlsl version
    arguments.push_back(L"2021");
    arguments.push_back(L"-T");        //target stage
    switch (stage)
    {
        case VK_SHADER_STAGE_VERTEX_BIT:
            arguments.push_back(L"vs_6_0");
            break;
        case VK_SHADER_STAGE_FRAGMENT_BIT:
            arguments.push_back(L"ps_6_0");
            break;
        default:
            throw std::runtime_error("Unknown shader stage!");
    }
    arguments.push_back(L"-E");        //entry point
    arguments.push_back(L"main");
    ComPtr<IDxcResult> compile_result;
    hres = dxc_compiler->Compile(&src_buffer, arguments.data(), (uint32_t) arguments.size(), nullptr, IID_PPV_ARGS(&compile_result));

But I still can’t debug at HLSL level: “Go to source” option is gray.

Is this caused by not having a disassembler in Renderdoc? It seems like I don’t have a disassembler to disassemble from spirv to hlsl. If it is, which executable I’m supposed to choose to do so?
