Wifi extender question

I didn't know a Chime Pro from Ring is a wifi extender and have bought one that's called TPLink Mesh Wifi Extender AC1750 Dual Band. I have done as directed on brochure to connect but it does not say 'connected' on my wifi settings as it does on my normal wifi setting. I don't know if I can have both showing connected though. Can anyone please tell me if it'll work or have I done my dollars. And if it will work would really appreciate help with making it do that
