Second google home mini in home assistant

I have one google home mini configured with home assistant. I used this article to configure it:

This works great i can control all the enitities that home assistant contains. Now i would like to setup a second google home mini that works independent of the first one. Is this possible and if so how? Can this be done by just following the setup for the second time

When i set the google home mini up the new one takes over the connection to home assistant and the older configured one does not have a connection to home assistant anymore. Does anyone have a solution or experience with this?

Are you adding both minis to the same Google account or separate ones? If the same account, it should just work with any number of minis. I have one in each room.
