Can I publish my game on GOG?

Hello, I'm considering publishing my game on GOG, but I have a few questions before I take the leap. Could you please clarify if there are any specific requirements or guidelines I need to follow in order to have my game listed on the platform? Also, I'm curious about the revenue split and payment terms offered by GOG. Additionally, how does the platform handle marketing and promotion for the games listed on it? Would it be possible to get some insight into the process of submitting a game for review and the potential timeline for approval? Thank you in advance for your help.
