Change environment domain (URL)

Hello,

am I somehow able to change the environment I wrongly set up in PowerBI? Even though I have only one environment in the Power Platform Admin Center, which is the one I want to use, somehow I was suggested to use another environment. I am not able to change the name of the environment to the one I have in PowerBI and I do not see the environment PowerBI connected to anywhere in the Admin Center. It is in my demo tennant so I have the full admin view. Do you have any suggestions of how to change the environment domain name in PowerBI?
