Configure readability-identifier-naming for const references

Clang Frontend clang-tidy
1

Hi, I want to configure readability-identifier-naming in a way that all function arguments that are constant (or pointing to something constant) are written with prefix “k” and CamelCase, like suggested by the Google style guide. However, I wonder how to configure this for const references and const pointers. Which options from clang-tidy - readability-identifier-naming — Extra Clang Tools 18.0.0git documentation shall I use? My current config can be found below. I am using clang-tidy-12.

Example (with all naming as suggested by clang-tidy-12 with the below configuration):
void MyFunction(
int k_my_var1, // spelling suggested as wanted by clang-tidy, not constant
int const kMyVar2, // spelling suggested as wanted by clang-tidy, constant
int const *my_ptr_1, // spelling suggested as wanted by clang-tidy, pointer is not constant
int *const kMyPtr2, // spelling suggested NOT as wanted by clang-tidy, pointer is constant but pointing to something not constant
int const *const kMyPtr3, // spelling suggested as wanted by clang-tidy, pointer is constant and pointing to something constant
int &my_ref_1, // spelling suggested as wanted by clang-tidy, not constant
int const &my_ref_2 // spelling suggested NOT as wanted by clang-tidy, constant reference
) { … }
