Where should a floating feedback button be placed for maximum use?

I am working on a project where my actionable buttons next and previous were placed to the bottom right and left corner of the browser. It wasn't a problem until floating feedback button was added to our application. This floating button has overlapped the next button and the flash messages that appear at the bottom right.

I have following possible options to solve this problem 1. Change floating feedback position to bottom left corner 2. Centralized next and previous button 3. Change flash message position from bottom right to bottom left.

I have already centralized the next and previous button, but I am not sure on swapping the position of floating button to bottom left cause I think the button will be ignored and no user will click on the button. Also, shifting flash message to the bottom left may cause the user to ignore important messages.
