How to upload to ImageKit via wappler API

For a Node.js project I am trying to upload images via a form to Imagekit (discovered it as it has been mentioned a few times on this forum). Essentially to use it as an image store for user uploads and then retrieve and display the optimized version using the various parameters imagekit allows.

Problem is i cannot figure out how to do the upload part. I have read the docs, have the public/private API keys but I realized i don't know how to create the API connection in wappler that would pass the file and upload it.
Maybe i am looking in the wrong place but I realized i couldn't figure out how to do this for uploads to any external platform (create the api connection) and a guide might already exist somewhere?

Any help would be greatly appreciated!
