Nginx proxy while reserving path - nginx

Question

http {
server {
listen 4443 ssl;
server_name {{hostname}};
port_in_redirect off;
ssl_certificate /etc/nginx/ssl/server.crt;
ssl_certificate_key /etc/nginx/ssl/server.key;
location / {

stream {
upstream app1 {
server 127.0.0.1:4443;
}
server {
listen 0.0.0.0:443;
proxy_connect_timeout 10s;
proxy_timeout 5m;
proxy_pass $target;
ssl_preread on;
}
access_log /var/log/nginx/access.log basic;
error_log /var/log/nginx/error.log error;
}
This is my nginx configuration.
This is part of a docker-compose setup. I proxy requests sent to https://hostname to the app1 container successfully.
Now my goal is to send requests sent to https://X.hostname to the app1 container, however to a different path.
For example:
Client sends request to https://A.hostname
Nginx forwards it to https://app1/my/path/
However the path is not being preserved, it's just forwarding it to https://app1
Tried many different solutions available online, and none worked.
