I am following document to configure the PCF: Create a model-driven app dataset component in Microsoft Dataverse - Power Apps | Microsoft Learn

I have deployed the sample code (with small extension) into sub grid (on form) and a sub grid (on dashboard). It works find in main form's subgrid, however, command bar is missing in dashboard's subgrid. I have confirmation from Product team that the missing command bar when using PCF in sub grid on dashboard is not supported at the moment. However, I think this is a helpful feature and cds-data-set-options should be supported on dashboards.
