I'm trying to follow the wiki instructions on how to modify an existing dialogue:

"
To modify an existing dialog in your module:

Open up the DialogEditor Icon.png Dialog Editor
Load an existing dialog from a project that yours inherits from (e.g. Data\Mods\DivinityOrigins_1301db3d-1f54-4e98-9be5-5094030916e4\Story\Dialogs\Tutorial\TUT_LowerDeck_OriginLohse.lsj if your project inherits from the Divinity: Original Sin 2 project)
Edit the dialog (in the example image I added an additional answer node for the Red Prince)
Save the dialog in your own project with the same file name, under "Data\Mods\{YourProjectFolder}\Story\Dialogs\"

"

I'm trying to search in my Data\Mods folder and I see a "DivinityOrigins_blahblahblah" folder but there are no files in it. I even created a new addon to specifically ensure that I was inheriting from and targeting the story.

Is there something I'm missing here?
