Good day everyone, I’m curious about getting a used Xbox One S as a DVD/Blu-ray/4K Blu-ray Player with Gaming Capability!

Before I set out to actually get one, I wanna know if an MS Account is Required to get the Needed Disk Player App for the Disk Playback to Function? Does it also require Internet access in any way to use disks regularly? Because I plan on keeping it off the Internet outside of Initial Updates
