I’ve been there many times, but not recently. I’ve never used a rope or noticed a permanent rappel station. Guide services and some private groups use ropes there. Most experienced climbers just scramble up and back down, unroped.
It’s class 3 rock. That’s not very difficult by itself. Snow and ice can make it much harder and more dangerous. I’m just guessing, but I would expect you to need crampons and axe at least part of the way to the notch. Above the notch, you might or might not be able to sneak around the snow and ice.
Watch the boards for trip reports. If conditions are right, you can do the entire trip in trail runners.
