WI-FI option is not showing

I brought a new Asus laptop which has latest WI-FI 6. I installed Kubuntu 21.04 alongside Windows 10 (dual boot). Furthermore, I can use both Ethernet and WI-FI in Windows, but I can only use Ethernet in Kubuntu. There is no wireless connection option is showing in networking options.
The same problem encountered when I was using Deepin OS in this laptop.

How to solve the problem ?

EDIT 2 :

I follow command line steps and downloaded Linux kernel 5.12.8 (1,3,4,6 line *.deb) to install kernel 5.12.8 which support WI-FI 6.

I reboot my laptop and it first shows
to select kernel version. (As by default it selected that kernel which I just installed). I hit enter, and then it shows

What should I do now ?
