Is Moonriver on MetaMask?

Excuse me, I've been doing some research on various cryptocurrency platforms and projects, and I came across Moonriver. I'm quite interested in exploring its capabilities and potential investments. However, I'm not entirely sure if Moonriver is integrated with MetaMask, which is my preferred wallet for managing my digital assets. Could you please clarify if Moonriver is indeed available on MetaMask, and if so, how I can go about accessing and interacting with it through the wallet? Your insight would be greatly appreciated.
