WordPress wp_localize_script nonce and ajax URL

I'm making an Ajax call in an Elementor site, and I'd like to use a nonce while doing it. Since my code is really simple, I didn't create a new JS file for it placed in Elementor's HTML widget, and I handle the request in the functions.php file.

I realized that the best way is to use wp_localize_script to make both the nonce and the Ajax URL available in the client side, but the function is asking for a file to register, and I don't know how to approach this, since there is no file to register and enqueue, functions.php is probably already enqueued?

How is it done? I've already read through so many tutorials and still didn't find that answer.

Any knowledge will be of great help. Many thanks.

wp_localize_script() doesn't care much which script handle you use as long as it is a valid one. You could use your theme's or Elementor's main script handle with the function to make the data available for your script. You'll need to check your theme's or Elementors source coude to find what these handles are.

Side note: It says on More information on the documentation that it is nowadays recommended to use wp_add_inline_script() to provide data to scripts as

wp_localize_script() should only be used when you actually want to localize strings.
