How to clear cookies with axum

[SorenHolstHansen]

I am doing cookie based authentication with leptos and axum, and for the logout server function I want to just clear all the cookies. So far I have not been successful

#[server(Logout, "/api", "GetJson", "logout")]
pub async fn logout() -> Result<(), ServerFnError> {
    let response = expect_context::<leptos_axum::ResponseOptions>();

    // First attempt: Just setting the SET_COOKIE header to an empty string.
    // This does nothing
    response.insert_header(header::SET_COOKIE, HeaderValue::from_str("").unwrap());

    // Second attempt: This just sets the mycookie header to an empty string
    let empty_cookie = Cookie::build("mycookie", "")
        .path("/")
        .finish();
    response.insert_header(header::SET_COOKIE, HeaderValue::from_str(&empty_cookie.to_string()).unwrap());

    // Third attempt: This makes the page try and download the response
    // Perhaps it should inherit some headers from the response
    response.overwrite(ResponseParts::default());

    Ok(())
}

#[component]
fn LogoutComponent() -> impl IntoView {
    view! {
        <form method="GET" action="/api/logout">
            <button type="submit">"Log out"</button>
        </form>
    }
}

I think I am doing something wrong, but I just can't figure it out

As I understand it, setting an empty value with an Expires field in the past is the standard way to delete a cookie. See here.
