What is the batcher fee for Minswap?

Can you please clarify what the batcher fee is for Minswap, and how does it work within the context of the decentralized exchange? I'm particularly interested in understanding if this fee is a fixed amount or if it varies based on certain factors, such as the amount of tokens being swapped or the current network congestion. Additionally, how does the batcher fee compare to other fees associated with trading on Minswap, and is there a way to minimize or avoid this fee altogether?
