Waterproof case biometric tape type?

Hello I got myself a Armor-X waterproof case for my brand new S26 Ultra. They supply some tiny circle of double sided tape for the biometric sensor on screen.

I was wondering if anyone knew what kind of tape it could be? Would like to get a sheet and make a whole screen area as it's bugs me when reading seeing the difference/ edge of the circle on screen, also feel the difference in thickness. I know it would make it a pain afterwards for removing the phone but thought maybe if setup right like a screen protector almost under the case plastic layer screen protector it would make it more seamless.

Thanks
