Adding categories

[Steffan72]

Hello is it possible to add more categories to the search forms...
I treid to change the form but im missing the structure in how to do that.

I want to add categories to:
t('Looking for a'),
'match_sex',
[
GenderTypeUserCore::MALE => '👨 ' . t('Man'),
GenderTypeUserCore::FEMALE => '👩 ' . t('Woman'),
GenderTypeUserCore::COUPLE => '💑 ' . t('Couple')
],
