To configure manual execution, use the `workflow_dispatch` trigger: ```yaml on: workflow_dispatch: inputs: environment: description: 'Target Environment' required: true default: 'staging' ``` This enables an "Run workflow" button in the GitHub Actions UI.

💬Answer

Workflow triggers are defined under the on: block. To configure manual execution, use the workflow_dispatch trigger:

on:
  workflow_dispatch:
    inputs:
      environment:
        description: 'Target Environment'
        required: true
        default: 'staging'

This enables an "Run workflow" button in the GitHub Actions UI.
