can't initialize iptables table `filter': Table does not exist (do you need to insmod?) - iptables is not present

I am trying to install NGINX and Certificate by following thisenter link description here in WSL

But at the Step 5: Allow Nginx Traffic, I am getting error after the command sudo ufw allow 'nginx http'.

The error we are facing is

WARN: initcaps[Errno 2] iptables v1.8.4 (legacy): can't initialize iptables table `filter': Table does not exist (do you need to insmod?)Perhaps iptables or your kernel needs to be upgraded.Skipping adding existing rule

While I listed the files in /etc/modprobe.d I didn't find iptable file

Can anyone help to resolve this.
