Auto website script required

The project is as such:

https://www.gov.uk/book-pupil-driving-test

Has a start now link

As such there is an e-captcha validation

https://www.access.service.gov.uk/authorize?client_id=pDCbrw8ab6iAt9N7bNZGybImRHcD8j&redirect_uri=https://dsa.dft.gov.uk/obs-web/login?app%3DOBS&response_type=code&scope=openid%20name%20profile%20email%20address%20phone&state=Df97kt

Once on that site - there are a number of test centres

(To register - https://www.gov.uk/register-book-driving-tests-for-pupils).

You can select 5 centres - as quick search - and then they want to be able to keep searching every 5 - 10 secs and lock / block the lessons.
So essentially need a macro / query to run on refresh to keep querying the site / search and displaying the available slots.
