How do I add a fusion network to MetaMask?

Excuse me, I'm a bit new to the world of cryptocurrency and I'm trying to figure out how to add a fusion network to MetaMask. Could you please explain the process in a step-by-step manner? I'm assuming I need to add a custom network, but I'm not sure where to find the necessary details like the RPC URL, Chain ID, and Symbol. Could you guide me through this process? Thank you so much for your help.
