How Can I Find a Button's Location Within a Spreadsheet With Google Apps Script?

I am creating a classroom attendance log in Google Sheets. I have a column with each student's name and a column for the time when they arrived in class. I want to include a button for every student that I can click to run a script that inserts the current time into the arrival time cell for that student. Is there a way to find the location of a button so that my script can insert the time into the appropriate cell?

Here's how I have my sheet set up: https://docs.google.com/spreadsheets/d/19wRj1zPGf1hm8PDUYtEF2XUxirhk2lIJbHAZF9e9YqE

Is there a better way to do this? I played around with the NOW() formula, but it updates every time I do anything else in the sheet. This might be a viable option if I could somehow force it to stay the same.

Based on my understanding, you want to get the cell row of the drawing that is being clicked to include the time entry for a particular student.

That is not possible, when you click a drawing/image, you are only clicking the drawing/image. It doesn't make the cell where the image located be active. Therefore, we cannot use the getActiveRange and getSelection method to locate the cell where the image is located.

One workaround that I could think of is to use checkboxes instead of drawings. When checkboxes are clicked, it makes the cell active.

Sample Code:

function onEdit(e) {
  
  const sheet = e.source.getActiveSheet();
  const cell = e.range
  
  // Check if checkbox was checked and there is no time-entry yet
  if (cell.isChecked() == true && cell.offset(0,-1).isBlank()){
    
    //Include time entry on the left side of the checkbox
    //var date = Utilities.formatDate(new Date(), 'America/Los_Angeles', 'MMMM dd, yyyy HH:mm:ss Z');
    var date = Utilities.formatDate(new Date(), 'America/Los_Angeles', 'HH:mm:ss Z');
    cell.offset(0,-1).setValue(date);
    
    // Uncheck the checkbox
    cell.setValue(false);
  } else if (cell.isChecked() == true) {
    // Uncheck the checkbox
    cell.setValue(false);
  }
}

You can change the format of your timestamp depending on your preference. In this example I only displayed the current time. See Working with Dates and Times

Output:

I reset the checkbox after setting the timestamp.
