I am trying to load an icon with my chrome extension, but when I try to unpack my extension, I get an error saying the following: "Could not load icon '../src/assets/images/checkmark-16.png' specified in 'icons'."

Below is my manifest. Does anyone know that I am doing wrong?

{
  "manifest_version": 3,
  "name": "Reminder-App",
  "version": "0.1.0",
  "description": "Reminder app for all your tasks",
  "action": {
    "default_popup": "index.html",
    "default_title": "Reminder App"
  },
   "icons": {
   "16": "../src/assets/images/checkmark-16.png"
 },
  "permissions": ["storage"]
}
