How do I transfer Astar to MetaMask?

Could you please elaborate on the process of transferring Astar tokens to MetaMask? I'm interested in understanding the steps involved and any potential challenges I might encounter. Specifically, I'd like to know if there are any prerequisites, such as setting up specific networks or ensuring that MetaMask supports Astar. Additionally, I'm curious about the estimated time it takes to complete the transfer and any associated fees. Clarifying these details would help me better navigate the process and ensure a smooth transition of my Astar tokens.
