Local Build Class is there but does not code hint

So I have a class I am creating in a local build of BJS. When I go to the playground I am able to access and initiate the class, but it does not show up in the code hinting.

I changed the index.ts in the correct src folder. Is there a additional area I need to change?

The code hinting is using preview.babylonjs.com/babylon.d.ts as source so it will not show up until the class will be merged to the nightly
