## 定义方式

```ts
export default definePlugin({
  extensionPoints: {
    "backup:tabs:create": (): BackupTab[] | Promise<BackupTab[]> => {
      return [
        {
          id: "foo",
          label: "foo",
          component: markRaw(FooComponent),
          permissions: [],
        },
      ];
    },
  },
});
```

```ts title="BackupTab"
export interface BackupTab {
  id: string; // 选项卡 ID
  label: string; // 选项卡标题
  component: Raw<Component>; // 选项卡面板组件
  permissions?: string[]; // 选项卡权限
}
```
