Email PDF of screen without (and with) a Flow

The need to send a screenshot (it could be a form, invoice or anything else) as an email attachment straight from Power Apps is highly useful.
The process actually is very simple using the PDF() function. Firstly, a temporary variable needs to be created with the file content and that used to form the email attachment. This one is to the user, but could be to any address.

With(
   {_PDF: PDF(ScreenName)},
   Office365Outlook.SendEmailV2(
      User().Email,
      "Subject here",
      "Body here",
      {
         Attachments: 
        {
            Name: "PDFFileName.pdf",
            ContentBytes: _PDF
        }
     }
  )
)

Note also you can send the same content to a Flow, but need to convert it to Base64.

With(
   {
      _PDF: 
      With(
         {
            _JSON: 
            JSON(
               PDF(ScreenName),
               JSONFormat.IncludeBinaryData
            )
         },
         Mid(
            _JSON,
            Find(
               ",",
               _JSON
            ) + 1,
            Len(_JSON) - 
            Find(
               ",",
               _JSON
            ) - 1
         )
      },
      AttachFileFlow.Run(
         _PDF,
         User().Email,
         "Test Subject",
         "Test Body",
         "TestFile.pdf",
      )
   )
)

then do a base64ToBinary conversion in the Flow. I have also added an action to create anew file in a SharePoint Library at the bottom.
