Httpx.AsyncClient how to update proxy on client?

Question

Python

In general, there is a code:

def rand_proxy()
    Подключается к базе, достаёт прокси и заканчивается:
    return prox

client = httpx.AsyncClient(proxies={'http': rand_proxy()}

And I don’t understand how you can update the proxy on the client, let’s say after 30 seconds

. If you know, you could not help)
