Enable C++23 on custom toolchain

Marmelade

Hello,

I would like some guidance on how to setup the STM32CubeIDE to allow me to use C++23 on the ARM toolchain I usually use.

The ARM toolchain is setup correctly but in the project's properties>C/C++ Build>MCU/MPU G++ Compiler>General, the language standard cannot go as high as iso or gnu C++20. Is there any way to write a value myself or do I have to use an external CMake.

Thanks for your help,
