Complexheatmap row boxes or grids are not visible

Question

I would like to see each row like this looking distinct grid

Such as this

This is my code which im running

Heatmap(heat, col = col_fun,name="Z-score", 
        show_row_names = TRUE, show_column_names = TRUE, cluster_rows = FALSE,
        cluster_columns = FALSE, show_column_dend = TRUE, show_row_dend = FALSE,
        column_title="Samples",
        column_title_side="top",
        row_names_side="left",
        row_names_gp = grid::gpar(fontsize = 8),
        
        column_title_gp=gpar(fontsize=10, fontface="bold"),
        column_title_rot=0,
        column_names_gp = gpar(fontsize = 20, fontface="bold"),
        row_dend_reorder = TRUE, column_dend_reorder = TRUE, clustering_method_rows = "complete",
        clustering_method_columns = "ward.D2", width = unit(100, "mm")
        )


decorate_heatmap_body("Z-score", {
  
  grid.rect(gp = gpar(fill = "transparent", col = "black", lwd = 2))
  
})

I get something like this below image where apart from top few rows all looks like one big block. How do i make them look like each row a separate block.

My data used for the above plot
