We need to enable Run workflows from fork pull requests to get workflow triggered.
- Go to setting of enterprise, organization or repository settings.
- Example URL of an organization settings URL: https://github.com/organizations/your-oganization-name/settings/profile.
- Go to Actions > Fork pull request workflows section
- Check Run workflows from fork pull requests
- Click Save

Example of workflow:

name: Run unit test workflow
on: pull_request # Pull request on any branches
env:

jobs:
  run_unit_test:
    name: Run unit test
    # Find more virtual environment. https://github.com/actions/virtual-environments
