how to get www site to automatically redirect to non-www

I'm trying to automatically redirect this site to non-www , I have setup a https certificate through certbot. At the moment I have 2 seperate domains one with www and one without, if a user is logged into the site without 'www' they have to login again when removing 'www' from the address, not sure how to config nginx and certbot, appreciate any help with this, I'd like to have both domains available but for the www.soundpro.city to redirect to soundpro.city.

nginx/sites-available/myconfig


server {
server_name 18.169.114.2 soundpro.city www.soundpro.city;


location = /favicon.ico { access_log off; log_not_found off; }
location /static/ {
root /home/ubuntu/djangoapp1;
}

location /media/ {
root /home/ubuntu/djangoapp1;
}

location / {
include proxy_params;
proxy_pass http://unix:/run/gunicorn.sock;
}







    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/soundpro.city/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/soundpro.city/privkey.pem; # managed by Certbot
    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot









}
server {
    if ($host = www.soundpro.city) {
        return 301 https://$host$request_uri;
    } # managed by Certbot


server_name  www.soundpro.city;
    listen 80;
    return 404; # managed by Certbot


}

this is my nginx.conf file :

user www-data;
worker_processes auto;
pid /run/nginx.pid;
include /etc/nginx/modules-enabled/*.conf;

events {
        worker_connections 768;
        # multi_accept on;
