Am I allowed to submit an IL run for Airport if I'm playing the demo?

If I play with my DS4, what would I have to say my platform is? Would it still be Mac or would I have to set it to Xbox One?

What would I say my platform is if I play with a PS4 Controller on my Macbook? (Running Catalina so there is built-in support for PS4 controllers in the OS and Roblox.) Would it be macOS/PC or Xbox?

I Submitted a request for Stepford County Railway (https://web.roblox.com/games/696347899/SCR) to be added but I haven't heard anything abut it. I sent it in about a month or 2 ago.

I want to get information so I can speedrun Minecraft for the first time but I need the in game time? How would I find that on MacOS?
