tmux command: [`respawn-window`](/en/tmux/latest/manual/respawn-window/)

```
LibTmux.Window.RespawnAsync(request: RespawnRequest?, cancellationToken: CancellationToken) -> Task
```

Restarts the command running in this window.

tmux refuses to respawn a window that is still running unless the
request kills it first, and killing it destroys every pane but one.

## Parameters

- `request` (`RespawnRequest?`): What to respawn, or null to reuse the original.
- `cancellationToken` (`CancellationToken`): Cancels the tmux command.
