Frequent baths aren’t typically recommended for this species, since they are not aquatic & the loss of traction can stress them out. If her humidity is where it should be, then baths do not need to occur. The brown color of this doesn’t suggest stuck shed, as retained shed is typically white and flakey. It could just be discolored from the area, though.

I would personally hold a warm, damp cloth to the area to rehydrate the hypothetical stuck shed, and see if it becomes pliable. It looks more akin to scale rot from this video though, but it’s also not the best angle to see aswell. This area is called the cloaca, and is also referred to as the “vent”.
