What is the margin mode in delta Exchange?

Excuse me, could you elaborate on the margin mode feature in the context of delta Exchange? As a trader, I'm interested in understanding how this feature works and how it might benefit my trading strategies. Specifically, I'd like to know if it allows for leverage trading, the risks associated with using margin, and how to properly manage my positions when operating in this mode. Additionally, I'm curious about any specific requirements or restrictions that might apply to using margin on the platform.
