Unsure about Release procedure. Will pushing the build binary to Live make the game available to buy on the Store?

I am a bit uncertain about the release process on Epic Store. I have the live build approved, but I did not yet push the binary to live. My understanding is that once I do that, it will become released and accessible to public, as the documentation hints. Is my thinking correct? What if I want to push other changes, for example to the store page texts, to Live, before making the binary accessible to public?

Will this Live push of the binary show the BUY button on the store page? Will I be effectively releasing my game before the release date this way?
On Steam there is an actual procedure you need to go through to actually Release the game for sale. Does Epic have something similar, or is the Live binary the way to release the game and will it bypass the actual release date, and release it sooner?
