Not able to find Switchbot locks after changing Switchbot account

Hi all,
I had to change the Switchbot account of my Switchbot locks. After removing the locks from old Switchbot account to the new Switchbot account, they of course did not work in Homeassistant - wrong username and password I guess. Anyway I removed the locks from the integration, and expected to add them again. That simple does not work.

I don’t ever get to a point where I can enter the new username and password. It seems as if the old username and password is still stored somewhere even if I removed the devices.

Can anyone help me to figure out how I “reset” the integration?
