Is Coinbase Apex?

Could you please clarify for me if Coinbase Apex is indeed a separate entity from Coinbase, or if they are somehow interconnected? I've heard some rumors that Apex is a subsidiary or a part of the larger Coinbase ecosystem, but I'm not entirely sure if that's accurate. Can you help me understand the relationship between these two companies, if any? Additionally, what services does Coinbase Apex specifically offer that might set it apart from Coinbase or other cryptocurrency platforms? I'm interested in learning more about the unique value proposition of Coinbase Apex in the cryptocurrency and finance space.
