Wifi option not available, Manjaro KDE on Macbook Air 2017

I installed Manjaro KDE on my usb, I have a Macbook Air 2017. The wifi option isn’t available, I presume I have to install a WiFi driver, I’m not sure how to do that, I am new to Linux.
I have a kernel version 5.8, I installed kernel header as well. I am currently connected to internet via usb tethering. Upon starting up for the first time, I thought Manjaro would give an option to install drivers, but it didn’t.


You need linuxZY-broadcom-wl

Replace the ZY with the Kernel Number you running on.
