How To Trigger GitHub Reusable Workflow On Specific Condition

I have a reusable workflow to run unit tests after each commit is pushed. However, I don't want to trigger it on each commit push now. Is there a way to run reused workflow when Tag Created or Pull Request Opened | When New Commit Pushed To Pull Request

Reusable Unit Test Workflow

name: Reusable Unit Test

env:
    # This will suppress any download for dependencies and plugins or upload messages which would clutter the console log.
    # `showDateTime` will show the passed time in milliseconds. You need to specify `--batch-mode` to make this work.
    MAVEN_OPTS: "-Dmaven.repo.local=.m2/repository -Dorg.slf4j.simpleLogger.log.org.apache.maven.cli.transfer.Slf4jMavenTransferListener=WARN -Dorg.slf4j.simpleLogger.showDateTime=true -Djava.awt.headless=true"

    # As of Maven 3.3.0 instead of this you may define these options in `.mvn/maven.config` so the same config is used
    # when running from the command line.
    MAVEN_CLI_OPTS: "--batch-mode --errors --fail-at-end --show-version"

    # Override when additional goals are necessary (such as `package assembly:single`)
    MAVEN_ARTIFACT_GOALS: "test"

    # IMPORTANT: Only override in client project when strictly necessary
    # NOTE: The order here is important. prepare-agent must be done before running tests
    MAVEN_GOALS: "clean org.jacoco:jacoco-maven-plugin:prepare-agent $MAVEN_ARTIFACT_GOALS"

Main Workflow

name: GitHub Actions Demo
on: [ push ]

jobs:
    unit-test:
        name: Unit Tests
        uses: ./.github/workflows/run-unit-tests.yml
        with:
            java-version: '17'
            java-distribution: 'corretto'
            java-cache: 'maven'
            maven-image: 'maven:3-amazoncorretto-17'
    integration-test:
        name: Integration Tests
        uses: ./.github/workflows/run-integration-tests.yml
        with:
            java-version: '17'
            java-distribution: 'corretto'
            java-cache: 'maven'
            maven-image: 'maven:3-amazoncorretto-17'
            skip-unit-tests: true

Do I need to use jobs.<job_id>.if? If so, how?

Thanks

I found the solution. Removing workflow_call is not the correct way to use reused workflows. If you need separate jobs for different events, we should use jobs.<job_id>.if or use something like this where you call reused workflows
