Which phones support DeX mode?

Can you tell me which phones are currently compatible with DeX mode? I've heard it's a great way to turn my phone into a desktop-like experience, but I'm not sure which devices are supported. Are there any specific models or brands that I should be looking out for? Also, is there any additional hardware required to use DeX mode, or can I simply enable it on my phone? I'd really appreciate any information you can provide on this topic.
