How much does KuCoin charge for margin trading?

I'm curious to know, could you please elaborate on the fees that KuCoin imposes for margin trading? As a trader, it's important for me to understand the costs associated with leveraging my trades on this platform. Are there any specific fees for opening or maintaining a margin position, and if so, how are they calculated? Furthermore, are there any hidden charges that I should be aware of before engaging in margin trading on KuCoin? Your insight would be greatly appreciated.
