Changed In Frappe JS File but Not Updated

I changed in desk.min.js file. Increased file size because i can’t upload profile picture and others file. Changed work if i use “sudo supervisorctl reload” command but problem is then if i use “bench start” it stopped showing log in terminal. So if i want to see log in terminal then i need to use " sudo supervisorctl stop all " and start the bench. If i use “sudo supervisorctl stop all” command then my changed in desk.min.js file disappeared. I use “bench build” also it also disappeared my changes.
