Is ontology on Coinbase?

Excuse me, could you please clarify if Ontology, the blockchain project focused on digital identity and data exchange, is currently listed on Coinbase, one of the largest cryptocurrency exchanges in the world? I'm curious to know if investors can buy and trade ONT tokens directly on this platform, as it would significantly impact its accessibility and liquidity in the market. Additionally, could you also share any insights or updates on the future possibility of Ontology being added to Coinbase, if it's not already available? Thank you for your time and attention.
