I use this approach:

get_data <- function(obj, assay='RNA') {
  wrap_data <- wrap_expression(
    counts = t(obj@assays[[assay]]@counts),
    expression = t(obj@assays[[assay]]@data)
  )
  wrap_data <- add_grouping(
    wrap_data,
    obj$seurat_clusters
  )
  wrap_data
}
get_data(seurat_object)

When I use get_data, it shows an errors as following. I don't know how to address it.

Error in t(obj@assays[[assay]]@DaTa) : trying to get slot "assays" from an object of a basic class ("character") with no slots
5.t(obj@assays[[assay]]@DaTa)
4.rownames(expression)
3.rownames(expression) %||% rownames(counts)
2.wrap_expression(counts = t(obj@assays[[assay]]@CountS), expression = t(obj@assays[[assay]]@DaTa))
1.get_data("seurat_object")
