nativeHeapProfilingNativeHeapProfilerOptions (optional) Experimental - Electron extension; not part of Chromium's TraceCategoriesAndOptions schema. Enables native (C/C++) heap allocation profiling for this recording. This is distinct from JavaScript heap profiling (see contents.takeHeapSnapshot()); it samples allocations made by Chromium and native modules. Unlike TraceConfig, this object has no included_process_ids field, so every traced process is profiled.
