KKBOX: switching between multiple KKBOX accounts

I have two kkbox accounts. Let’s say I have an A account and a B account. I log in to kkbox from roon with A account. When I log out and log back in, I cannot enter my account and am automatically logged in with the A account. There is no way to log in with the B account. How can I log in with the B account?
