How to change email address associated to squarespace account?

My squarespace website was created under a gmail account that is now compromised by scam emails (I still have access, but I'd like to switch to be safe). I need to switch from my old gmail address to a new gmail address, but I'm unable to do. The only similar option Ive seen is switching between social accounts / different log in options, but NONE of these are helpful to this situation. I just need to update my account with a new gmail address!
