What is the transaction fee for SushiSwap?

Excuse me, could you please clarify the transaction fee associated with using SushiSwap? I'm interested in understanding the cost structure involved in executing trades or swaps on the platform. Is there a standard fee that applies to all transactions, or does it vary based on factors such as the size of the trade, the current network congestion, or the specific tokens being exchanged? Additionally, are there any other fees or charges that users should be aware of when utilizing SushiSwap for their cryptocurrency transactions?
