Your screenshot is of one of the legacy components (i believe it's what was called the "Apps Portal", though my memory is pretty fuzzy as it was already being actively phased out by the time I started as a developer). In modern versions it's not generally accessible to any end users or even developers under normal circumstances, though may still be reachable to some extent via unusual workarounds.

That is the very old legacy designer environment and is only supported to keep apps from < 2015 alive. Feel free to ignore that.
