According to the calcite design website we can add intelligence to the vs code for calcite by entering
"html.customData": [ "./node_modules/@esri/calcite-components/dist/extras/vscode-data.json" ]
in the .vscode/settings.json
I did just that, but it didn't work. Did I miss something?

@BenElan @KittyHurley Suggestions? Thank you.
