Does Coinbase support Polymath?

As a crypto enthusiast and potential investor, I'm curious to know if the renowned cryptocurrency exchange Coinbase supports Polymath. Polymath, being a leading platform for security token issuance and management, seems to be gaining traction in the blockchain space. Given Coinbase's reputation and extensive listing of digital assets, it would be beneficial for Polymath's users if Coinbase offered support for their tokens. So, does Coinbase currently support Polymath, and if not, are there any plans in the future to integrate it into their platform?
