How to enable __float128 on IntelliSense?

[Phantom-Trigger]

My IntelliSense doesn't work with __float128. My platform is Windows, compiler is gcc11.2.0 from winlibs, C/C++ Extension Version is 1.10.8. I've tried all possible options for "Intelli Sense Mode" but all still have the same issue as #6574 (i.e. gives an IntelliSense error: identifier “__float128” is undefined). But it do compiled and run successfully. Did I misconfigured something?
