Get option value (api setting) in block

I am looking to modify the value of a wordpress options inside a gutenberg block.

Here is a succinct overview of the option:

function capacity_theme_options_styling()
    {
        register_setting('capacity_styling', 'capacity_options_styling', 'capacity_validate_sanitize_reset_styling');

        add_settings_section(
        'capacity_section_styling_background_color',
        esc_html__('Background color', 'capacity-plugin'),
        'capacity_section_styling_background_color_html',
        'capacity_styling'
        );

        
        add_settings_field(
        'capacity_background_color',
        esc_html__('Background color', 'capacity-plugin'),
        'capacity_background_color_html',
        'capacity_styling',
        'capacity_section_styling_background_color',
        [
        'label_for' => 'capacity_background_color',
        'class' => 'capacity-row',
        ]
        );

        ...

        }
