Xgb.plot.shap 2D plots



I noted in the R package of XGBoost for the xgb.plot.shap function they have a which argument, either 1d or 2d. 2d is not yet implemented. Does anyone know when this might be implemented?

Apologies if this is wrong place to discuss this. I thought it might be more useful discussing it here than raising it as an issue in github.
