Timestamp on multiple sheets in one workbook as well update the sheet if another sheet updated the one sheet

I have the following timestamp script in my workbook. The way it is written it is only updating the staff effort sheet.

https://docs.google.com/spreadsheets/d/17-75DRIfKICQYVE2MIUQ7ljZEs4GM-vJXEP4wAXmOgk/edit?usp=sharing

What I would like to have happen is the following.

• If the project list sheet gets edited it will add a time stamp to colunm 22
• if the staff effort sheets gets edited, it will add a timestamp to column 12
• all other sheets will be ignored

function onEdit(e) {  let range = e.range;  let col = range.getColumn()  let row = range.getRow();  let sheetName = e.source.getActiveSheet().getName();  if (sheetName == 'Staff Effort'&& col != 50 && row > 12) {    let timestamp = Utilities.formatDate(new Date(),"GMT-5","M/d/yy h:mm a");    let sheet = e.source.getActiveSheet();    sheet.getRange(row,50).setValue(timestamp);  }}function onEdit(e) {  let range = e.range;  let col = range.getColumn()  let row = range.getRow();  let sheetName = e.source.getActiveSheet().getName();  if (sheetName == 'Project Tracking'&& col != 22 && row > 1) {    let timestamp = Utilities.formatDate(new Date(),"GMT-5","M/d/yy h:mm a");    let sheet = e.source.getActiveSheet();    sheet.getRange(row,22).setValue(timestamp);  }}
