How Can You Create iPhone Shortcut for Showing File Without iCloudDrive/Dropbox?

Appreciate the recent post regarding creating a Shortcut to show a vaccination card, thank you. Is there a way to do the same with a local-only file? I.e. no iCloudDrive and no Dropbox, the scanned file is local on iPhone only. In the action GetFile tapping to turn off ShowDocumentPicker apparently only works if iCloudDrive or Dropbox is enabled.
Do not have and do not want either iCloudDrive or Dropbox.
