I am a bit confused about how we should actually use the multi select feature on the DataGrid2. You can link a microflow to the selection changed but typically you do not want to react to the selection changed event, but you want to have a button on top of the data grid that does something with the selection. Is the only option that you keep track of the selection somewhere in an entity to get that behavior? That feels like quite cumbersome just to get multiselect on a grid.
