How to profile React Native source code using Xcode/Instruments/Time Profiler

$

We're using React Native 0.59.10 and React-Redux 5.0.7, and are experiencing a CPU-bound performance issue, in which our Redux actions are taking ~0.25s to complete.

We've profiled using the Time Profiler configuration in Instruments, but none of our JS code is symbolicated.

Remotely debugging in Chrome seems to just debug the "remote inspector" page, which is entirely unhelpful.

Is there a way to build/attach a source map, or symbolicate the memory addresses seen below, to the JS function names/calls?
