I am using 7.8.0 version of kibana and elasticsearch. on the front i have configured nginx 1.19 as a reverse proxy.
i have put following configurations on nginx.conf but when i hit `https://DNS:4443` (Nginx url) it ends up with an error
`https://DNS:4443/31997/bundles/...js` files with `401 error.` I have put a configuration like if url does not have embed query string it should gives 401 response.

error_page 420 = @validrequest;
return 420;
}
location / {
error_page 420 = @validrequest;
if ( $arg_embed != "true" ) { return 401; }
return 420;
}
location @validrequest {
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Authorization "ApiKey API_KEY_DATA";
proxy_pass https://KIBANA_ACTUAL_DSN:8080; # actual kibana URL
}
```
