What is arbitrum 7 day withdrawal?

Excuse me, could you please clarify what exactly "Arbitrum 7 day withdrawal" refers to? I'm curious to know if it's a specific feature or policy related to Arbitrum, a popular Layer 2 scaling solution for Ethereum. Does it mean that there's a seven-day waiting period before funds can be withdrawn from a particular platform or service that utilizes Arbitrum? Or is it perhaps related to a specific type of transaction or withdrawal process on the Arbitrum network? I'd appreciate any insight you can provide.
