Custom Font Not Detecting In Customizer

Hi,

I followed your documentation for custom fonts. https://docs.generatepress.com/article/adding-local-fonts/

But the font is not showing in the customizer.

I added this to style.css of child:

@font-face {
    font-family: geomanist;
    src: url(fonts/geomanist/geomanist-light-webfont.eot);
    src: url(fonts/geomanist/geomanist-light-webfont.eot?#iefix) format("embedded-opentype"), url(fonts/geomanist/geomanist-light-webfont.woff2) format("woff2"), url(fonts/geomanist/geomanist-light-webfont.woff) format("woff"), url(fonts/geomanist/geomanist-light-webfont.ttf) format("truetype"), url(fonts/geomanist/geomanist-light-webfont.svg#geomanistlight) format("svg");
    font-weight: 300;
    font-style: normal
}

I added this to functions.php of child:

add_filter( 'generate_typography_default_fonts', 'tu_add_local_fonts' );
function tu_add_local_fonts( $fonts ) {
    $fonts[] = 'geomanist';
    return $fonts;
}

Is this is because that I'm using custom directory name for my child theme? Child theme name and directory name is custom.

Note: Typography is disabled on the generatepress options.

Thanks!
