Chrome block all downloads initiated from sandboxed iframe

Hi all, 

Recently Google Chrome updated their functionality for sandbox iframes with preventing downloads at sanbox iframe.  "We plan to prevent downloads initiated from sandboxed iframes, and this restriction could be lifted via an 'allow-downloads' keyword, if present in the sandbox attribute list."

 

As Microsoft Teams - presonal/ tab app are invoked their downloads from sandbox iframe, all downloads are failed at Google Chrome version 83 and hire . Does anyone know , Microsoft Teams dev will enable the flag "allow-downloads"  for Teams sandbox atribute list ?
