Couldn't connect Cudy wu1400

Hi everyone, I hope you are doing well. I have installed dietpi [Native PC (UEFI)] on my laptop. But I can’t connect wifi with my USB network adapter. I have installed git, dkms, make and then installed the driver using these commands:

sudo apt install git dkms

git clone GitHub - cilynx/rtl88x2bu: rtl88x2bu driver updated for current kernels.

sudo dkms add ./rtl88x2bu

sudo dkms install rtl88x2bu/5.6.1

then restarted my laptop but SSID’s are not showing in ‘dietpi-config>network-adapter>wifi’. How to fix it?
