How to set Vulkan Validation Layer filter via the vk_layer_settings.txt?

Question

I have just activated the Vulkan Best Practices Validation and due to that I get the following warning:

Validation Layer(WARNING): Validation Warning: [ UNASSIGNED-BestPractices-vkCreateInstance-specialuse-extension-debugging ] Object 0: VK_NULL_HANDLE, type = VK_OBJECT_TYPE_INSTANCE; | MessageID = 0x822806fa | CreateInstance(): Attempting to enable extension VK_EXT_debug_utils, but this extension is intended to support use by applications when debugging and it is strongly recommended that it be otherwise avoided.

Naturally, I don't need to see this in a debug build, so I'd like to filter this message out in debug builds. According to the docs one can use the message id filter with the vk_layer_settings.txt:

By default, the settings file must be named vk_layer_settings.txt and reside in the working directory of the targeted application.

I have checked the current directory with std::filesystem::current_path() (pointing to /my/project/dir/build/src/) and put the layer settings file there, and I have also tried to put it next to the debug .exe file (at /my/project/dir/build/src/Debug/MyProject.exe).

The contents of my file are:

khronos_validation-message_id_filter = "UNASSIGNED-BestPractices-vkCreateInstance-specialuse-extension-debugging"

I have tried to use the id instead of the message name:

khronos_validation-message_id_filter = "0x822806fa"

Neither of the two has worked at either of the locations. How do I correctly use this filter then?

If this is in any way important, the project is build with CMake with the main file residing at /my/project/dir/CMakeLists.txt and the build done through

cd /my/project/dir/build
cmake ..

And finally compiling the solution via Visual Studio 2022

Looks like I just had a typo in my file.

The file had to be at /my/project/dir/build/src (i.e. the place I got from std::filesystem::current_path()) and the content now is

khronos_validation.message_id_filter = "UNASSIGNED-BestPractices-vkCreateInstance-specialuse-extension-debugging"

(in my question it was ...validation_message... instead of ...validation.message...)
