Is gnosis chain L2?

Could you please clarify for me whether the Gnosis Chain is considered an L2 solution? I've been hearing a lot about Layer 2 solutions in the cryptocurrency space, and I'm trying to understand how Gnosis Chain fits into this picture. Could you explain the key features and functionalities of Gnosis Chain that make it potentially classified as an L2? Also, if it's not an L2, could you explain what type of blockchain it is and how it differs from Layer 2 solutions? Thank you for your assistance in clarifying this for me.
