AverageHeatmap() function in Seurat v5

[ziyuan-ma]

Hello, thanks for developing this wonderful visualization package! I have encountered some issues passing the Seurat v5 object to AverageHeatmap() function. Could you please advise how should I pull data from the data layer instead of from slot? Thank you!

> AverageHeatmap(object = pbmc,
+                markerGene = markers$gene)
As of Seurat v5, we recommend using AggregateExpression to perform pseudo-bulk analysis.
