Return Type Preact Forward

I make tsx component in fresh preact but have a error said it need a return type, what is the return type for a forwardref?
66 | const Checkbox = forwardRef<HTMLInputElement, CheckboxProps>((props, ref): JSX.Element => {
| ^^^^^^^^ this symbol is missing an explicit type
|
= hint: add an explicit type annotation to the symbol

info: all symbols in the public API must have an explicit type
docs: https://jsr.io/go/slow-type-missing-explicit-type

const Button = forwardRef<HTMLButtonElement, ButtonProps>((props,ref)=> {
return (
<button>a example </button>
)}
