How do I upload a mod to Steam Workshop?

Hello. I've just created my first mod for POE2, and I've uploaded it to NexusMods, which was quite simple. 

 

But uploading to steam workshop seems like a different beast entierly. Does anyone have any information on how to get a mod on the Workshop?

 

Thanks in advance.
