Github Actions - Reached heap limit Allocation failed

Question

Github Action gives my this error for the last "run: npm run build"

FATAL ERROR: Reached heap limit Allocation failed - JavaScript heap out of memory
Error: Process completed with exit code 1.

My workflow file

name: Node.js CI

on:
  push:
    branches: ['master']

jobs:
  build:
    runs-on: self-hosted

    strategy:
      matrix:
        node-version: [16.x]
        # See supported Node.js release schedule at https://nodejs.org/en/about/releases/

    steps:
      - uses: actions/checkout@v3
      - name: Use Node.js ${{ matrix.node-version }}
        uses: actions/setup-node@v3
        with:
          node-version: ${{ matrix.node-version }}
          cache: 'npm'
      - run: npm i
      - run: npm i
        working-directory: client
      - run: npm run build --if-present
        working-directory: client

I think this is the solution

env:
   NODE_OPTIONS: "--max-old-space-size=4096"

But it didn't work yet im not sure i've to add "-" before the env and the exact position of it... I did it under "run: npm run build --if-present working-directory: client" but didn't work.
