Typescript function parameter into returnType

Here's my function:

export const useSomething = <Data extends object>(
    func: (values?: Data) => Promise<any>,
    name?: string
)

export const useSomething = <Data extends object>(
    func: (values?: Data) => Promise<any>,
    name?: string
)

It returns as below

return {} as returnType<Data,Name>

return {} as returnType<Data,Name>

I want to use the function in the below syntax:

useSomething<SomeInterface>(TestFunction, 'test')

useSomething<SomeInterface>(TestFunction, 'test')

and not

useSomething<SomeInterface,'test'>(TestFunction, 'test')

useSomething<SomeInterface,'test'>(TestFunction, 'test')

🤨 How can I create the type Name - from the value of the parameter name- and use it in the returnType thing so I avoid typing 'test' twice in the call?
