Nginx configuration behind nginx reverse proxy

I have an Nginx with Docker for my development environment with HTTP and HTTPS, here's the configuration:

listen 80;listen 443 ssl;set_real_ip_from 10.0.0.0/8;real_ip_header X-Real-IP;real_ip_recursive on;location / {    try_files $uri @rewriteapp;}location @rewriteapp {    rewrite ^(.*)$ /app.php/$1 last;}location ~ ^/(app|app_dev|app_test|config)\.php(/|$) {    fastcgi_pass php-upstream;    fastcgi_split_path_info ^(.+\.php)(/.*)$;    include fastcgi_params;    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;    fastcgi_param HTTPS $https;}

I want to test HTTP and HTTPS in my local environment but in production, I have an Nginx reverse proxy in front with:

upstream app_upstream {  server app:80;}server {server_name $APP_DOMAIN;listen 443 ssl;ssl_certificate /run/secrets/app_cert.pem;ssl_certificate_key /run/secrets/app_key.pem;proxy_set_header HOST $host;proxy_set_header X-Forwarded-Proto $scheme;proxy_set_header X-Real-IP $remote_addr;proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;location / {    proxy_pass http://app_upstream;}}

I want the reverse proxy to accept the only HTTPS and forward to the application nginx but my PHP application behind is receiving $_SERVER['HTTPS'] = ""

I also want to keep the SSL certificate only on the reverse proxy, how do I pass HTTPS from reverse proxy to Nginx to PHP?
