how to trash files in Google Photos via Appscript?

Question

I wrote the attached script to read a json formatted text file, and trash listed files in my google drive. I want to do the same for files in Google Photos, but a I can't see a way to access them from Appscript. I am fairly new to this. Would anyone have tips on accessing Google Photos via Appscript?

function trashFilesInList(){
  var count = 0;
  var errCount = 0;
  var filesjson = JSON.parse(importTextFromDrive());
  for (var i = 0; i < filesjson.length; i++) {
    var filename = filesjson[i].title;
    try{
      var file = getFileFromName(filename);
      if (file !== ""){
        file.setTrashed(true);
        count++;
      }
    }
    catch(err){
      errCount++;
    }
  }
  Browser.msgBox(count + " files trashed. " + errCount + " errors.")
}

function getFileFromName(fileName){
  try{
    var files = findFilesInDrive(fileName);
    if(files.length === 0) {
      return "";
    } else if(files.length > 1) {
      return "";
    }
    var file = files[0];
    return file;
  }
  catch(err){
    return ""
  }
}

function importTextFromDrive() {
  var fileName = "PhotosDeleteList.txt";
  var files = findFilesInDrive(fileName);
  if(files.length === 0) {
    displayToastAlert("No files with name \"" + fileName + "\" were found in Google Drive.");
    return;
  } else if(files.length > 1) {
    displayToastAlert("Multiple files with name " + fileName +" were found. This program does not support picking the right file yet.");
    return;
  }
  var file = files[0];
  var contents = file.getBlob().getDataAsString();
  return contents;
}

//Returns files in Google Drive that have a certain name.
function findFilesInDrive(filename) {
  var files = DriveApp.getFilesByName(filename);
  var result = [];
  while(files.hasNext())
    result.push(files.next());
  return result;
}

//Displays an alert as a Toast message
function displayToastAlert(message) {
  SpreadsheetApp.getActive().toast(message, "⚠️ Alert"); 
}
