I have personal and business Google Drive accounts. Mind Map Maker currently opens and saves files to my personal Google Drive. How can I have Mind Map Maker point instead to my business Google Drive account - so I can open / save from that account instead? When I attempt to open a Mind Map Maker .json file from my business Google Drive account, Mind Map Maker gives an error message. When I choose the Documents > Open and Documents > Save As and select "Google Drive", I get a file menu from my personal Google Drive account, with no means to switch to my business account.
