Help? Exchange Cambodian Riel (KHR) to Thai Baht (THB) in early April 2024

I know this topic have been asked before, and I'm checking if someone can assist me with swapping out my KHR to THB. For those that would visit Cambodia for whatever reason. I have 231,500 KHR (~ $57 USD) which my parents forgot to exchange way back when. I'll be heading to Bangkok in April 2024 with no stop in Cambodia.

If you're able to buy/exchange my KHR for THB, that would be great. Thanks.
