How to set default Typography?

How to set default typography options? This is what I am using right now:

Group_Control_Typography::get_type(),
[
    'name' => 'typography',
    'scheme' => Scheme_Typography::TYPOGRAPHY_1,
    'fields_options' => [
        'typography' => 'custom',
        'font_family' => [
            'default' => 'Playfair Display',
        ],
        'font_size' => [
            'default' => [
                'unit' => 'px',
                'size' => '17',
            ],
        ],
        'font_weight' => [
            'default' => '700',
        ],
        'line_height' => [
            'default' => [
                'unit' => 'px',
                'size' => '50',
            ],
        ],
    ],
]

But this is not working when loading the page. But working after clicking on typography options
