Call External API in Forge Custom UI

Hi @PeterYu! Thank you for your answer. I am looking for a way to deal with file upload. Currently I am facing this problem: Can't post multipart form data file in new NodeJS runtime - #3 by GyorgyVARGA
I am looking for a workaround, maybe to upload the image directly from the client, but that is kind of like an antipattern here, because I am exposing my keys on the client. Btw I am using Cloudinary to store the images. If the multipart form data error doesn’t get resolved I will use this guide to do this inside the React app:
Upload Images with React-Dropzone
