How to use parallel_tests in github actions

I'm trying to use parallel_tests in my github action to run my test suite but I was not able to find a proper solution. The official docs has one but it is for gitlab:

https://github.com/grosser/parallel_tests/wiki/Distributed-Parallel-Tests-on-CI-systems

Any help would be appreciated thanks!

This was what I used to get it solved. Note: There are some other omitted parts such as the setup for ruby, postgresql, sqlite, etc.

name: "Lint and Test"
jobs:
  test:
    runs-on: ubuntu-latest
    timeout-minutes: 30
    services:
      redis:
        image: redis
        ports: ["6379:6379"]
      postgres:
        ports: ["5432:5432"]
    steps:
        //omitted setups
      - name: Setup Parallel Database
        env:
          RAILS_ENV: test
          PGHOST: localhost
          PGUSER: postgres
        run: |
          cp config/database.yml.example config/database.yml
          bundle exec rake parallel:create
          bundle exec rake parallel:rake[db:schema:load] || true
      - name: Build and test with rspec
        env:
          RAILS_ENV: test
          PGHOST: localhost
          PGUSER: postgres
          APP_REDIS_URL: redis://localhost:6379
          MINIMUM_COVERAGE: 80
        run: |
          bundle exec parallel_rspec --verbose spec
