am I uploading my update via "edit game" right? Because that's the only way I can upload files. but there is no update button or add an update or add another version, like, there you can either hide the old versions or delete them or add it.

•let's say there is a PC version, I uploading  it next to the previous one without deleting the old one, but the platform understands that this is a new version due to the note that this is version 0.8, when the old one was 0.7. Is that how it works???? 

•and then I create an update and mark these versions, and it turns out that the site understands that these are the latest updates Or what?

after adding versions to the development log, the button and the ability to download files disappeared.

if I had found a detailed update guide somewhere, I wouldn't have asked this question. but I didn't find it, if it exists at all.
