How to get clang-format working in Visual Studio

Visual Studio has native integration for clang-format since 15.7 prev1.

I'm using 15.9.9 and nicely see the configuration in the options. Visual Studio Configuration C++ Formatting

From my understanding, as 'Google' is selected in the formatting style, it should use either my .clang-format file which is in the root of my checkout or fallback to the hard-coded configuration with name 'Google'.

However, if I format my file: Ctrl+K, Ctrl+D, my file gets formatted using Whitesmiths; which is the brace configuration of my Visual Studio formatting.

Did I forget to configure something that allows me to use clang-format or is something horribly going wrong? If it is the last one, I appreciate some debugging tips.
