## Why are you seeing this issue?
This is a [support escalation](https://github.com/github/support/blob/main/ticket-processes/escalating-outside-support.md#escalating-to-engineering-and-product-teams)! You can find out more about expectations on communications and response times in the [on-call docs](https://thehub.github.com/epd/engineering/incident-response/support-to-engineering-escalation-process/#support-escalation-response-procedures-and-best-practices).

## Issue

Customer reports that while the [Other services and CI systems](https://docs.github.com/en/copilot/how-tos/copilot-sdk/auth/server-to-server-tokens#other-services-and-ci-systems) section of the [Server-to-server authentication](https://docs.github.com/en/copilot/how-tos/copilot-sdk/auth/server-to-server-tokens) page of the [Copilot SDK](https://docs.github.com/en/copilot/how-tos/copilot-sdk/) documentation says you should:

> Create a GitHub App with the **Copilot Requests** repository permission set to **Read & write**.

But when creating a GitHub App there doesn't seem to be any such repository permission in the UI.

**To Reproduce**

Steps to reproduce the behavior:
1. Go to `...`
2. Click on `...`
3. Scroll down to `...`
4. See error

**Expected behavior**

The documented **Read & write** **Copilot Requests** repository permission should exist.

**Screenshots**

N/A

**Additional context**

I have tried creating a GitHub App myself and did not see this permission.

从链接的 Server-to-server authentication 页面开始，重点查看“Other services and CI systems”部分，并将其中关于 Copilot Requests 权限的指导与 GitHub App 创建 UI 进行比较。查看相关的 Copilot SDK 身份验证文档和支持工单背景，以确定预期行为。当文档与 GitHub App 权限一致，并且面向客户的差异得到处理后，即视为完成。
