Saved to wrong google drive

There’s a little popup in the right of the document that says “Enable saving to Drive”.
I kinda want to save my work there, so obviously I click “allow” so that way I can save to my personal email/drive (which is the one I used to make the account). Unfortunately, I previously at some point apparently connected the drive choice to my old school email, which has since been deactivated.

As you can see when I click the second green “allow” button, instead of allowing me choose which drive or even saving it the original email connected, it redirects me to a popup for my old school email. There doesn’t seem to be an option anywhere to disconnect Kami from my school drive.

edit: I can manually save it by using the “download” function, it’s just kind of annoying.
