io.github.libtmux.Window.Window.displayPopup(shellCommand: String) -> void
```

Shows a popup over this window, running a command in it.

tmux draws a popup for a client, so this needs one attached; on a detached session tmux
reports that it has no current client.

tmux expands {@code #(...)} in this command before a shell sees it, and shell quoting does
not prevent that. Pass any interpolated value through {@link TmuxFormats#literal} unless you
mean it to be expanded.
