What do sloths smell like?

Could you elaborate on the olfactory qualities of sloths? Have researchers conducted any studies to determine their specific scent? Are there any common descriptors used to characterize their smell? Is it similar to other animals in the rainforest, or does it possess a unique aroma? Furthermore, do sloths have a natural odor that is appealing to humans, or is it more of a neutral or unpleasant scent? I'm particularly curious about how their scent might vary based on their environment, diet, or other factors. Thank you for considering my inquiry.
