I got my client component as a input, i use it on my main generator page but i also want to use it somewhere else (for instance in my chat page which is a server component atm)

That’s correct, but it’s only needed if that Client Component is using Client Only supported APIs like the window object (document, local storage, etc) or some APIs like Date, random() and a couple more.

If your client component has “use client” and you’re getting a hydration error, then yes, use dynamic and you can even provide a fallback while the Client is first mounting the component {ssr : false, loading : <Skeleton/>}

For client components that do not have conflicts with Client Only APIs, that’s not necessarily, unless you want to delay the rendering of the component to only happen on the client for some reason.
