Nginx proxy_pass implementation

[JasonGH17]

I have made a webapp using leptos and axum, today I had to deploy the app but I had to set it up to go through nginx.
I was instructed to serve the app on a server separate from the server running nginx, and I have to redirect all the requests made to the nginx server with the route prefix "/ems" to the other server running leptos.
I got the nginx configuration running but then realized the requested HTML page won't prefix its request routes with "/ems", which means it would never find any of its resources to be able to run the app. Is there a way I can fix this?

For more context, the leptos server is running on 192.168.2.160:3000, and this is the nginx configuration block responsible for handling the requests:

location ~* ^/ems/(.*)$ {
	proxy_set_header X-Forwarded-For $remote_addr;
	proxy_set_header Host $http_host;
	proxy_pass http://192.168.2.160:3000/$1$is_args$args;
}
