command not found: react-scripts (PS: yarn2(berry) workspaces)

Question

Working on a yarn2 powered monorepo with two workspaces common and app. I've declared typescript and react-scripts as devDependencies in root's package.json ; and declared typescript and react-scripts as peerDependencies in app's package.json.

However, running yarn start gives the error

command not found: react-scripts

Any idea how to go about this?

Sidenote

react-scripts has peerDependencies on react which I've provided in root workspace's dependency section.

attaching package.json for root:

{
  "name": "monorepo",
  "packageManager": "[email protected]",
  "private": true,
  "dependencies": {
    "@testing-library/jest-dom": "^5.16.4",

Not sure if this is a hack, but solved this using https://yarnpkg.com/getting-started/qa#how-to-share-scripts-between-workspaces

added this to root's package.json

 "scripts": {
    "g:start": "cd $INIT_CWD && react-scripts start",
    "g:build": "cd $INIT_CWD && react-scripts build",
    "g:test": "cd $INIT_CWD && react-scripts test",
    "g:eject": "cd $INIT_CWD && react-scripts eject"
  }

updated this in app's package.json

 "scripts": {
    "start": "yarn g:start",
    "build": "yarn g:build",
    "test": "yarn g:test",
    "eject": "yarn g:eject"
  }

PS:not really sure why react-scripts isn't available in app workspace even though its specified as a peerDependency :/
