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
