Can I get VAT refund in Korea?

I'm currently traveling in Korea and I've made some purchases that are eligible for VAT refund. However, I'm not entirely sure how the process works or if it's even possible to get a refund in Korea. Could you please provide some information on this matter? Specifically, I'd like to know if there are any specific requirements or steps I need to follow to apply for a VAT refund, and if there are any restrictions or limitations that I should be aware of. Additionally, could you tell me if there are any common issues or challenges that travelers often face when trying to claim their VAT refund in Korea? I would greatly appreciate your help in clarifying this matter for me.
