Load GCode file question

Sorry if this has been addressed somewhere else, first time user…
How can you open a previously saved gcode file or a gcode file created with another software (like Vectric) to run on my new JTech laser using Lightburn?

I do not see gcode format as an import or open option.

It’s near the “Start” button - “Run GCode”. There’s no option to open it because it’s not an editable format any more. LightBurn will simply stream it to the machine.
