Betaflight problems with frysky receiver

I am using betaflight on chrome book with the chrome extension and this is my first fpv drone (iflight CidoraSL5) with a taranis Q X7 receiver and my problem is that my receiver will not connect to betaflight and move with the things on the receiver tab on betaflight. Please help I have been trying for a while.
