How to forward http to https with Lightsail Load balancer

I currently have an app built on a lightsail server. I used Amazon certificate to create SSL https with a load balancer. Under inbound traffic I have to protocols

Http Enabled
Https Enabled.

When I go to https://app.myexample.com sure enough I get an SSL certificate all good. However I'd like to forward http to https. When you go to http://app.myexample.com you get no secure connection (obviously). How can I force http to go to https?

I was going to do it with an .htaccess file but I read somewhere that it should be done through the Load Balancer. Unfortunately all documentation for this is only for Elastic Beanstalk. I'm using Lightsail. How can I accomplish this on lightsail?

There is no way to do it on Lighsail services level, but!
AWS load balancer pass http_x_forwarded_proto header further.
It is possible to do redirect on your app, webserver level.
I'm using nginx web server, there this configuration looks like this

server {
    listen 80;
    listen [::]:80;
    location / {
        if ($http_x_forwarded_proto = "http") {
            return 301 https://$server_name$request_uri;
        }
    }
       
}
