Export Bot Code
Inventor does not generate code for your bot that can be used independently. There is no way to export your bot's code, because that code doesn't exist.
All Inventor flows act as a "configuration" that is fed into the Inventor runtime, which then runs your flows using Inventor's internal block logic. This configuration data is accessible to you (through the flow editor and exports), but cannot be turned into a standalone executable or collection of code files to host your bot separately.
You can export a text-based representation of your bot in bot settings in order to recreate your flows, but it is not working code.
