html, css file upload to Arduino 33 IoT

Dear All,

I would like to use the Arduino 33 IoT as a webserver and store the index.html and *.css and *.jr files on the board as I was able to do with the ESP32 using the ESP32 Sketch Data Upload in the Arduino IDE. It does not have to be same way of cause, but is there a way to do so.

Many thanks Karsten

Edit: sorry I just realized that this should go into the Nano 33 IoT subforum, may I kindly ask someone to move it? Thanks
