Where can I redeem Apex Coins?

Excuse me, could you please elaborate on where exactly one might go to redeem Apex Coins? I'm interested in understanding the process and any specific platforms or websites that support this type of transaction. Is there a specific section within the Apex Legends game itself where these coins can be redeemed, or are there external websites or retailers that offer this service? Additionally, are there any specific steps or requirements that need to be met in order to successfully redeem Apex Coins? I appreciate your help in clarifying this matter.
