How do I share my location with a friend?

I accepted a location sharing request from a friend and accepted it, but apparently I can't see it in the 'Find My' app. It's supposed to show a list of people that's sharing locations with me but I don't see a 'Peoples' tab at the bottom. Also when I click at a friend's contact, it doesn't show me the option of sharing my location with him, even when I am sharing my location. (Basically I can only accept location sharing requests but can't send them)
