Change MIDI Device Name? (XIAO_ESP32S3)

Hmm, am I meant to just put this at the top of my sketch (or the setup() function)?

Or does this need to be in a separate .c file?

More specifically does it need #include "usb_names.h" in there? (this throws an error when trying to compile for the ESP32S3)

I just tried putting it at the top of the sketch, and did the required trick to get my computer to forget the previous name, but still can’t get a new name to stick.
