I’m currently trying to utilize the functions found [in the native access api for glfw](https://www.glfw.org/docs/latest/group__native.html), but there doesn’t seem to be a way to check what backend glfw is actually using, at first i thought `_GLFW_<platform>`, ex `_GLFW_X11` would be it, but it seems to be undefed at some point. Thanks in advace.
