Inability to add mail attachment from Dataverse field through Power Automate

[SrShet]

I need to attach a file from Dataverse table in the power automate flow - Gmail Send Mail action.

i am unable to find the exact steps to do this, 

Below are the steps i have followed.

1. i am getting a row from Dataverse table which has the attachment column (DataType -> File). using List Rows action.
2. i am using this in Send Mail Action --> Attachment content.
3. i see the attachment column in Dataverse table stores  a GUID, instead of the actual image content.
4. This is Not working since the actual attachment is not sent in the email.6. i even tried using the "Download a file or an image " action , to get the file content from the dataverse table and pass its output to the send email action- Attachments content field. This is throwing an error: "
   404 - File or directory not found."
   ".

   please assist me on how to get the attachment stored in Dataverse table and use it in Gmail-Send mail action.
