Is Injective a cosmos chain?

Could you please clarify for me whether Injective is indeed a Cosmos chain? I've heard rumors about its integration with the Cosmos ecosystem, but I'm not entirely sure about its exact status. Could you elaborate on its relationship with Cosmos, if any? Also, if it is a Cosmos chain, could you explain what advantages it might offer compared to other blockchains? I'm really interested in understanding the unique features and capabilities of Injective within the larger Cosmos framework. Thank you for your assistance in clarifying this matter.
