Typescript, Sankey: Missing attributes in SankeyNodeDatum / SankeyLinkDatum Type

[philemonSchulz]

When using the Sankey Component with TypeScript, the onClick Method returns either a "SankyNodeDatum" or "SankeyLinkDatum" object.
When logging, a lot of attributes like "id", "sourceLinks" or "targetLinks" are displayed. However, the defined types only allow for "color", "formattedValue", "index" and "value".

It would be great if the other attributes are represented in the type as well.
