How to exchange the fingerprint sensor

Hey Guys my fingerprint sensor isn't responding anymore (probably water damaged),

so I want to exchange it. In the teardown, the fingerprint sensor is pretty complicated to exchange. Is there an easier way?

And what do I need to do it (tools etc.)

I'm a beginner so please tell me how difficult this was.

Thanks Guys
