How to use HTTPS in my Digital Ocean Laravel Deployment

I deployed my Laravel-5.8 project to DigitalOcean and it works fine as:

http://laravelproject.net

But since I am using Azure AD and Socialite. Azure AD does not allow http but https

/etc/nginx/sites-available/default

server {
listen 80 default_server;
listen [::]:80 default_server;

# SSL configuration
#
# listen 443 ssl default_server;
# listen [::]:443 ssl default_server;
#
# Note: You should disable gzip for SSL traffic.
# See: https://bugs.debian.org/773332
#
# Read up on ssl_ciphers to ensure a secure configuration.
# See: https://bugs.debian.org/765782
#
# Self signed certs generated by the ssl-cert package
# Don't use them in a production server!
#
# include snippets/snakeoil.conf;

root /var/www/html/laravelproject;

# Add index.php to the list if you are using PHP
    # index index.php index.html index.htm;
# index index.php index.html index.htm index.nginx-debian.html;

server_name 123.130.32.49;

location / {
	# First attempt to serve request as file, then
	# as directory, then fall back to displaying a 404.
	 try_files $uri $uri/ /index.php$is_args$args;
	# try_files $uri $uri/ =404;
}

# pass PHP scripts to FastCGI server
#
location ~ \.php$ {
	include snippets/fastcgi-php.conf;
#
#	# With php-fpm (or other unix sockets):
	fastcgi_pass unix:/var/run/php/php7.4-fpm.sock;
#	# With php-cgi (or other tcp sockets):
#	fastcgi_pass 127.0.0.1:9000;
}

# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
location ~ /\.ht {
	deny all;
}
}

How do I make it use https instaed of http?

Thank
