Using Kami for business and personal accounts

I’m starting my own small business and I have a personal google account and a business account. I understand how to create separate profiles for Chrome to let Kami access each google drive respectively, but does that mean I have to pay for two separate subscription plans? I’ve chosen the Pro plan under my business account in order to use OCR and merge/split pdf files. Since I’m already paying for that functionality, how can I use those services on my personal google drive documents?
