"Delete" button when DataGrid selection(s) made

On DataGrids, there is an option to let users Add rows, with an “Add” button placed at right above the Grid, next to an optional Search field. But the only way a user can delete rows is to select the first cell of a row’s checkbox (itself not all that obvious) and then somehow know that pressing their Delete key will delete the row.
Suggest a “Delete” or “Delete Selected” button (green box below) to mirror the “Add” button for balanced UX clarity.
