how to enable c++header-parsing action for bazel toolchain

Question

I'm writing my own bazel toolchain. As part of the toolchain, I decided to add the cmd action "-process_headers_in_dependencies".

I understood that the action for this feature is "c++-header-parsing". To enable this feature, I read that this feature apply only for toolchain that support modules. """ Run the compiler's parser on a header file to ensure that the header is self-contained, as it will otherwise produce compilation errors. Applies only to toolchains that support modules. """

and how can I add it to my toolchain?

Note - I look into bazels default toolchain, I saw that they add a feature for the action "c++-header-parsing" and passing the flags "-fsyntax-only" and "cx++-header" Maybe it belongs.

Thanks a lot.

As I have added above, I have tried to add the feature parse_headers with the following action "c++-header-parsing" which didn't work for me. I still haven't been able to compile the header only with the cmd line flag and raise an error for failure.
