In CellScatter The <scale> argument of guides() cannot be FALSE.

[Rfriedmancolumbia]

Dear Github team,

In the workflow in https://satijalab.org/seurat/articles/integration_introduction

I get the following Warnig Message:

> p1 <- CellScatter(aggregate_ifnb, "CD14 Mono_CTRL", "CD14 Mono_STIM", highlight = genes.to.label)
Warning message:
The `<scale>` argument of `guides()` cannot be `FALSE`. Use "none" instead as of ggplot2 3.3.4.
ℹ The deprecated feature was likely used in the Seurat package.
  Please report the issue at <https://github.com/satijalab/seurat/issues>.
