A screenshot of a conversation with GitHub Copilot. The user asks if multiple events, like pull_request and workflow_run, in a GitHub Actions workflow are connected using boolean logic, specifically whether all triggers must occur or if just one suffices. Copilot responds by explaining that the events are connected with an OR logic, meaning the workflow will trigger if any one of the events happens. The interface includes a prompt bar labeled "Ask Copilot" with icons for attachments and actions.
