Power Automate attaching a document to new task

[mbemis]

Hi,

I am trying to create an automated flow in Planner using power automate.  Currently, I have an automated flow set up where when a task under a bucket is marked completed, it automatically copies that task to the next bucket.  What I can't figure out is how to get it to automatically attach a specific document to the newly created tasks.  Any suggestions would be appreciated.

Thanks
