Why in Zoho Flow was upload file to Workdrive left out of the box?

We are trying to use Zoho Flow to upload 1 file that comes to Google Drive each time 1 customer sends a document... The service we are using can only put the files in Google Drive, so we have a Flow that triggers with this file arriving to GDrive and we need the file to come to Workdrive, still, it's craze how Workdrive has a lot of actions availabe in Zoho Flow except to upload a file? and if you check all the other file manager apps like Dropbox, Box, GDrive itselfe, One Drive, Egnyte, etc, you will find some can create folders, some fetch file but NONE can upload files? what's the point? we want to move our Zaps to Zoho Flow but with this enormous limitations we will have to stay with Zapier.
