I actually had to do exactly that a few weeks ago. What I ended up doing is:

I got everything working. Below I have my code which needs to be cleaned
up. I used the --libcurl flag to produce the libcurl c code, and it worked

Since I can't save the cookie file to the ESP32 in a file format, how do I
store the cookie and reuse it? Can I put it in a buffer?
