Add Google Font on "Police Title" and "Police Body" lists in "General Styles"

Hi

I would like to add the Google Font “Museo” on the lists “Police Title” and “Police Body” in “Fonts” in “General Styles” (Enfold Settings)

I added this code in Quick CSS :

add_filter( 'avf_google_heading_font',  'avia_add_heading_font');
function avia_add_heading_font($fonts)
{
$fonts['Museo'] = 'Museo';
return $fonts;
}

add_filter( 'avf_google_content_font',  'avia_add_content_font');
function avia_add_content_font($fonts)
{
$fonts['Museo'] = 'Museo';
return $fonts;
}

But I have no results. Can you explain me please what I must do ?

Thanks a lot for your help!
