How do I add BigTime to MetaMask?

As a cryptocurrency enthusiast, I'm curious about the process of adding BigTime tokens to my MetaMask wallet. Could you guide me through the steps? I'm familiar with using MetaMask for other tokens but BigTime seems to have a unique process. Would I need to add a custom token address? Also, is there a specific network I should be connected to while performing this action? I'd appreciate any detailed instructions to ensure a smooth and secure addition of BigTime to my MetaMask wallet.
