Can I buy ICO on Coinbase?

Excuse me, I'm a bit new to the world of cryptocurrency investments and I've been hearing a lot about ICOs recently. My question is, does Coinbase offer the ability to purchase ICO tokens? I understand that Coinbase is a leading cryptocurrency exchange, but I'm not sure if they facilitate the purchase of tokens during initial coin offerings. Could you clarify if this is a service they provide? If not, could you recommend any other reliable platforms where I could potentially participate in ICOs? Thank you for your time and assistance in this matter.
