Laravel Routes Isn't working for user uploaded files - laravel

Question

I'm trying to get Laravel application called Acellemail to work with nginx. It has issues with uploaded content. There seems to be some kind of encoding on the public URL which I can't figure out how to write a nginx rewrite rule for.
So the URL looks like this,
https://app.example.com/assets/YXBwL3RlbXBsYXRlcy82M2RmOWQ5ODAzZmEzL2ltZw/welcome-5.png
Actual path to the file on the server is this,
/var/www/app.example.com/html/storage/app/templates/63df9d9803fa3/img/welcome-5.png
Each time I upload a new template, it creates a new folder inside /var/www/app.example.com/html/storage/app/templates
And part of the YXBwL3RlbXBsYXRlcy82M2RmOWQ5ODAzZmEzL2ltZw portion in the public URL changes. Nginx returns 404 errors on these URLs.
Nginx config,
server {
server_name app.example.com;
root /var/www/app.example.com/html/public;
index index.php;
location / {
try_files $uri $uri/ /index.php?$query_string;
}
location ~* \.(ico|css|js|gif|jpe?g|png)(\?[0-9]+)?$ {
expires max;
log_not_found off;
}
location ~ \.php$ {
include snippets/fastcgi-php.conf;
fastcgi_pass unix:/var/run/php/php8.0-fpm.sock;
fastcgi_param SCRIPT_FILENAME $realpath_root$fastcgi_script_name;
include fastcgi_params;
fastcgi_read_timeout 300;
}
location ~ /\.ht {
deny all;
}

}
server {

return 301 https://$host$request_uri;
} # managed by Certbot
listen 80;
server_name app.example.com;
return 404; # managed by Certbot
}

Thanks for help in advance!
Tried to route with nginx rewrite rules. But it's not ideal.
