chisr -Your bot can directly send and receive files with users in the personal context, also known as personal chats, using Teams APIs. In order to send and receive files in your bot, you have to set the supportsFiles property in the manifest to true. This property is described in the bots section of the Manifest reference. The definition will look like this: "supportsFiles": true. If your bot doesn't enable supportsFiles, this features won't work.

Thanks!

This is not a published application, the users talk to the bot through the link from the registered bot Portal. So I will have to add my app as described here ? -  https://docs.microsoft.com/en-us/microsoftteams/platform/sbs-file-handling-in-bot?tabs=visualstudio&tutorial-step=5

      Thanks.
      It talks about sending an attachment (this works fine for me with HERO card).. My problem is - receiving an attachment (the url is private instead of pre-authenticated for a few minutes).

        I added the bot as Teams App with manifest ("supportsFiles": true), but still I get "403" error when trying to access the downloadUrl. Can you please help?
