```
LibTmux.Session.GetWindowAsync(target: string, cancellationToken: CancellationToken) -> Task<Window?>
```

Reads one of this session's windows by target.

A target naming a window in another session answers null rather than
that window: the question asked is which of this session's windows it
is, and tmux resolving it elsewhere is not an answer to that.

## Parameters

- `target` (string) — A tmux window target inside this session.
- `cancellationToken` (CancellationToken) — Cancels the tmux command.

## Returns

The window, or null when this session has no such window.
