IdStory Identity Manager

Button for download attachment added to the bulk action detail.

Base logic is same as @kopro developed. It means metadata for download are stored in operation result.
I compiling part of download url on BE now (rights reason ... I need to use different REST endpoint).

For show link on target entity (Export/Import agenda, Report agenda, ...) I uses info cards and ownerId/type.
I created info card for Export/Import entity.
Download button is show in modal bulk action dialog and in operation result too.

Result Http code must be 206 and parameters of the result must be:

• attachmentId (for back compatibility)
  or
• downloadUrl
• ownerId
• ownerType
