I see. Thanks for checking on that! I updated with a `loadSymbolsFromPseudoProbe` function. That loads the pseudo probe names based on the function range start address and pseudo probe address. I used a lower_bound to get the first pseudo probe of the function address, and traverse up through the inline tree to get the top-level function.
