How to use the roosterjs-editor-types.Alignment.Center function in roosterjs-editor-types

export default function setAlignment(editor: Editor, alignment: Alignment) {
    let command = DocumentCommand.JustifyLeft;
    let align = 'left';

    if (alignment == Alignment.Center) {
        command = DocumentCommand.JustifyCenter;
        align = 'center';
    } else if (alignment == Alignment.Right) {
        command = DocumentCommand.JustifyRight;
        align = 'right';
    }

    editor.addUndoSnapshot(() => {
        execCommand(editor, command);
        editor.queryElements(
            '[align]',
            QueryScope.OnSelection,
            node => (node.style.textAlign = align)
        );
    }, ChangeSource.Format);
}

        handleChange: (editor) => setAlignment(editor, Alignment.Center)
    },

        onClick: editor => setAlignment(editor, Alignment.Center),
    },

    onClick: editor => setAlignment(editor, Alignment.Center),
};

document.getElementById('alignCenterButton').addEventListener('click', function() {
        setAlignment(getCurrentEditor(), Alignment.Center);
    });
