Wordpress accessible from / and Symfony from /my-other-site/

I have a huge difficulty to achieve what I want to do on Nginx.

For a client, I have a blog using WordPress and a marketplace using Symfony 5.4. PHP version is 7.4 FPM.

The blog is under folder /var/www/blog/ with user and group www-data:www-data and should be accessible from https://my-domain.com

The marketplace is under folder /var/www/marketplace/ with user and group www-data:www-data and should be accessible from https://my-domain.com/marketplace/

I try a tone of different configurations found on the internet or using ChatGPT (just in case) without success.

Each time I've got a blog working or not and the marketplace is not found or I've got the error "file not found".

Could someone help me to have a basic idea of how to implement it? The basic configuration will be enough.

I will really appreciate your help :)

EDIT:

Here is my last try. Wordpress is working but when I try to access to https://my-website/symfony/ I've got a 404 not found of Wordpress.

I found a solution using this server configuration below:

server {
    listen [::]:443 ssl ipv6only=on http2;
    listen 443 ssl http2;

    ssl_certificate /etc/letsencrypt/live/my-website.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/my-website.com/privkey.pem;

    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem;

    server_name my-website.com;
    root /var/www/wordpress;
    index index.php app.php index.html;

    location /symfony {
        root $symfonyRoot;
        rewrite ^/symfony/(.*)$ /$1 break;
        try_files $uri @symfonyFront;
    }

    location ~ ^/assets/(.*)$ {
        rewrite ^/assets/(.*)$ /symfony/assets/$1 permanent;
    }

    location / {
        try_files $uri $uri/ /index.php?$args;
    }

    set $symfonyRoot /var/www/symfony/public;
    set $symfonyScript index.php;

    # This is for the Symfony application
    location @symfonyFront {
        fastcgi_pass 127.0.0.1:9000;
        # include /etc/nginx/fastcgi_params;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $symfonyRoot/$symfonyScript;
        fastcgi_param SCRIPT_NAME /symfony/$symfonyScript;
        fastcgi_param REQUEST_URI /symfony$uri?$args;
    }

    # This is for the wordpress app
    location ~ \.php {
        fastcgi_pass 127.0.0.1:9000;
        fastcgi_index index.php;
        fastcgi_param PATH_INFO $fastcgi_path_info;

    }
