## Add MR Approved Trigger Configuration UI for Flows and Agents ### Summary Introduce a trigger configuration interface that allows users to set up an **MR Approved** trigger for their flows and agents — enabling automation to fire when a merge request is approved — directly from the GitLab UI. --- ### Design Figma: https://www.figma.com/design/8dIIoI6h78WTjXbUTp0yOI/Agent-Workflow-Catalog?node-id=13039-101954&t=ClpBtTt9a7co3cbp-1 --- ### Background The backend implementation for the `merge_request_approval_operation` audit event (filtered on `action: approve`) is tracked in [#592456](https://gitlab.com/gitlab-org/gitlab/-/work_items/592456). Once users can select **MR Approved** as a trigger type for flows and agents, they need a corresponding UI to configure and manage this trigger. This issue covers the frontend work to surface the MR Approved trigger in the **New Trigger** form under `Automate > Triggers`. --- ### Problem Without a configuration UI for the MR Approved trigger, users cannot: * Set up automation that fires when a merge request is approved (e.g., to run a pre-merge checklist agent) * Configure a flow to draft release notes when an MR is approved * View or manage existing MR Approved triggers from the GitLab UI --- ### Proposed Solution Extend the **New Trigger** form under `Automate > Triggers` to support **MR Approved** as a selectable trigger type. The UI should: * Display **MR Approved** as an option in the trigger type selector * Show relevant context or help text explaining when the trigger fires (on `merge_request_approval_operation` with `action: approve`) * Persist and display the trigger correctly when viewing an existing trigger configuration --- ### Acceptance Criteria - [ ] **MR Approved** is available as a trigger type option in the New Trigger form - [ ] Selecting **MR Approved** shows appropriate configuration UI and help text - [ ] The trigger is persisted and displayed correctly when viewing an existing trigger - [ ] The trigger only fires on MR approval events (not on approval removal) - [ ] UI matches the design spec
