The Add to Cloud button does not show the Zoho Docs workspaces

Dear All,

Regarding the new button in zoho mail 'Add to Cloud' I would like to ask you the following:

When I receive an email with an attached file, when I push the 'Add to Cloud' button then it shows me a pop up window called Cloud Picker with three options Zoho Docs, Google Drive, DropBox.

In the Zoho Docs choice why it does not show me the workspaces which are shared with the other users and shows only my folders?

What can I do in case that I want to add the file in a workspace? Do I have to download it first and then to upload it again?
