Hello, I'm curious to learn if there's a way to specify recording parameters programmatically to xctrace. The docs, (in particular, create-parameter) imply that there's a mechanism for defining parameters and then specifying their values on the command line. From https://help.apple.com/instruments/developer/mac/current/#/dev494862765 : <create-parameter> Element Creates a parameter specific to this instrument. **Parameters show up in the UI and command line as recording options.** However, I only ever see these recording options in the UI. Latest Xcode15 beta 6 xctrace doesn't seem to mention anything else about recording parameters, from what I was able to tell. This is true for both custom instruments (where I defined create-parameter myself), and for 1st-party instruments such as Time Profiler (e.g. high-frequency-sampling). As a workaround I've been able to make custom instruments that import the relevant schemas and mark them as dependencies/required-inputs (then I can set the individual options). Is this the expected workflow for recording options? Am I misreading the docs? Just to clarify -- these parameters DO in fact appear from the UI, but are absent from xctrace . Thank you!
