I hope this codebase helps you to solve the problem.

async function sendBookingRequest() {
    setIsLoading(true); // Start loading before making the request
    try {
        const response = await axios.post(
            "https://danilo2588.pythonanywhere.com/book",
            {
                requested_date: date,
                hours: bookedHours,
                business: cancha,
                phone: cellphone,
            },
            {
                headers: {
                    Authorization: "1234567890123456789012345678901234567890",
                },
            }
        );
        setConfirmation(response.data); // Handle successful response
        setStepper(7);
    } catch (error) {
        console.log(error); // Log or handle the error
    } finally {
        setIsLoading(false); // Stop loading after the request
    }
}

And you can refer this documentation for axios configuration. https://axios-http.com/docs/post_example
