Changing label attributes in Dash Cytoscape

If I want to change the styling attributes for edge labels in a Dash Cytoscape, how should I add it in the stylesheet, because I am not familiar with JavaScript. Is it something that I should modify in:

                'selector': 'edge',
                'style': {
                    # The default curve style does not work with certain arrows
                    'curve-style': 'bezier',
                    'width': 10,
                    'label': 'data(id)',
