GCC supporting extensions?

[ghost]

Tried to switch to VSCodium. c/cpp tools from microsoft not available in market place. Read about it now and microsoft don't allow that extension on openvsx. Clangd was recommended as an alternative extension. I have cross compiling to do for STM32 microcontrollers using bare metal ARM GCC toolchain using Makefile based workflow(can check out my STM32 repo).

Might sound silly, but can clangd be configured to work with gcc somehow. The language server here works much better than ms-cpptools.

Or alternatively if there's a way to install ms-cpptools on vscodium?

OS: Garuda Linux (so got access to AUR)
