How create custom hook for login/register with e.preventDefault()

I want create custom hook for login and register functions because its best practice DRY (don't repeat yourself) I use the same function in /login and in AuthModal.tsx Here is my function for register

async function register(e: React.FormEvent) {
    e.preventDefault()
    if (email && password) {
      try {
        const response = await supabase.auth.signUp({ email: email, password: password })
        if (response.error) throw response.error

        if (response.data.user?.id) {
          const { error } = await supabase
            .from("users")
            .insert({ id: response.data.user.id, username: username, email: email })
          if (error) throw error

          userStore.authUser(response.data.user.id)
          setSuccess("Check your email")
        }
      } catch (error) {
        console.error("register - ", error)
        setError("Error")
      }
    }
  }

async function register(e: React.FormEvent) {
    e.preventDefault()
    if (email && password) {
      try {
        const response = await supabase.auth.signUp({ email: email, password: password })
        if (response.error) throw response.error

        if (response.data.user?.id) {
          const { error } = await supabase
            .from("users")
            .insert({ id: response.data.user.id, username: username, email: email })
          if (error) throw error

          userStore.authUser(response.data.user.id)
          setSuccess("Check your email")
        }
      } catch (error) {
        console.error("register - ", error)
        setError("Error")
      }
    }
  }

How do I create custom hook for it - when I tried do this I got an error that tells me that I need 3 arguments instead of 2 (it was login and password but it requires also e) that uses for e.preventDefault() I have this form

 <form className="flex flex-col gap-y-2" onSubmit={authAction === "Login" ? login : register}>
            <Button type="submit">Login</Button>
</form>

 <form className="flex flex-col gap-y-2" onSubmit={authAction === "Login" ? login : register}>
            <Button type="submit">Login</Button>
</form>
