# RequestClose

Renders a button that starts the cancelable native close-request lifecycle.

## Signatures

```ts
export declare function RequestClose<const Options extends CloseOptions, const Host extends HostResult = never>(options: Options, host?: Dom.HostOverride<Dom.RenderHostProps<Options, CloseInternalProps<Options>>, Options["content"], Host>): Fx<RenderEvent, Renderable.Error<Options | Host>, Renderable.Services<Options | Host> | Scope.Scope | RenderTemplate>;
```

## Why

Consumers can intercept a real `cancel` event before the dialog closes.
`controls` selects native `command="request-close"` and disables the Fx click
fallback; omit it when native dialog commands are unavailable.

## Ownership and lifetime

Running the Fx owns handlers by Scope; dialog registration remains owned by
the corresponding `Content` Scope.

## Examples

```ts
import { Effect } from "effect"
import * as Dialog from "@typed/ui/Dialog"

const program = Effect.gen(function* () {
  const state = yield* Dialog.makeState({ open: true })
  return Dialog.RequestClose({ state, content: "Cancel" })
})
```
