Why is BNB gas fee so high?

Could you possibly explain to me the reasons behind the relatively high gas fees associated with BNB? I've noticed that compared to other cryptocurrencies, the transaction costs seem significantly steeper, and I'm curious as to what factors might be contributing to this? Is it due to high demand for transactions on the Binance Smart Chain? Or could it be related to the complexity of the transactions themselves? I'd appreciate it if you could shed some light on this matter for me.
