Automate podcast upload

I’m looking to automate the upload of my podcast episodes. SoundCloud has been working well for this, but it doesn’t allow me to keep episodes private, which is a problem because I need an authorization step. Ideally, I’d like the episodes to stay private until a separate automation approves them for posting.

The final goal is to publish the podcast on Spotify, so it doesn’t have to be SoundCloud specifically. I’m just wondering if anyone is automating podcast uploads (especially track uploads) with Make.com and which app they’re using—preferably something other than SoundCloud.
