My apologies if this is a naïve question, is it possible to host the cytoviewer <shiny.appobj> class instance of a list, with nested ui and server components, to shinyapps.io or Posit connect/cloud?

Our images, masks, and cell-level metadata for the CytoImageList and SingleCellExperiment objects contain sensitive information. And unfortunately our collaborators don't use R, but would greatly benefit from the interactive visualization and exploration of multi-channel images and segmentation masks hosted remotely on a Shiny server URL.

For example, in the tutorial Bioconductor html vignette, the app is the <shiny.appobj> class instance of a list that I would like to privately share and deploy with our custom data:

library(cytoviewer)
library(cytomapper)

# Load example datasets 
data("pancreasImages")
data("pancreasMasks")
data("pancreasSCE")

# Use cytoviewer with images, masks and object
app <- cytoviewer(image = pancreasImages, 
                  mask = pancreasMasks, 
                  object = pancreasSCE, 
                  img_id = "ImageNb", 
                  cell_id = "CellNb")

if (interactive()) {

  shiny::runApp(app)

  }

Any suggestions? Thank you!
