Where can I buy ICP Dex?

Excuse me, could you please tell me where I can purchase ICP Dex? I've been hearing a lot about it lately and I'm quite interested in adding it to my crypto portfolio. Is there a specific exchange or platform where I can find it? I'd also appreciate it if you could give me some pointers on how to safely navigate the process of buying it. I'm still a bit new to the cryptocurrency world and I want to ensure that I'm making informed decisions. Thank you in advance for your help!
