Enable Saving to Drive Error

Whenever I open a PDF with Chrome, it automatically opens in Kami but it always gives me this notification: “Enable Saving to Drive”

The problem is that I have allowed Kami to automatically upload and save PDFs in my drive. See the photo for this in which you can see that I enabled the option for automatic save and upload. Yet, I keep getting this notification and I need to click “allow” in order to let Kami save it.

Can you guys fix this? Or am I doing something wrong?
