Progress bar falt with storage_multiupload() even with options(azure_storage_progress_bar=TRUE)

Hi,

First of all, thanks again for the great R interface to Azure, you provide, and your strong support.

I was wondering how could I display the progress bar of the following Job :

` storage_multiupload(container = contAC, src=paste0(img_out_path, "/*"), dest=folder_name, use_azcopy=FALSE, recursive = TRUE)`

Indeed, even if I have run before the following command : `options(azure_storage_progress_bar=TRUE)` , nothing is printed to the prompt.
Sometimes in a RShiny app, but not during the execution of a single command in the prompt), it says : `creating background pool`, but nothing more.

Is it because I have not enough files to send, or that my connection is to fast ?
Or is it cause of I do not use properly the `options()` command ?
Do you have any recommandations ?

Thanks in advance for your help,
Sincerely yours
