Teensy 4.1 + magjack neet jquery file on teensy itself

[unbreakmat]

Hi im running a offline webserver on my teensy 4.1 with the ethernetjack.
I have this file :
https://code.jquery.com/jquery-3.6.3.min.js

this is an online file buth my teensy doesnt have an active internet connection (so only offline possibilities, no browsing or surfing the web possible)

1. how can i place this file on my teensy local?
2. how can i let my webserver code refer to this file so that i can include it in my webserver like this:

const char HTTP_SCRIPT[]      =   "<script src='https://code.jquery.com/jquery-3.6.3.min.js'></script>";

im guessing something like

 const char HTTP_SCRIPT[]      =   "<script src='../jquery-3.6.3.min.js'></script>";

this is the code that i use for my webserver:

server.on("/", HTTP_GET, [](AsyncWebServerRequest * request) {
    handleRoot(request);
  });

void handleRoot(AsyncWebServerRequest *request) {
  String page = HTTP_HEAD_START;
  page += HTTP_SCRIPT; /*link to script!?*/
  page+= HTTP_BODY

  request->send(200, "text/html", page);
}

any help would be greatly appreciated!
