Video Doorbell (1st Gen) wiring

Hi Have just been given a Video Doorbell (1st Gen) wanted to know what i need to do to get power to the unit as I don't fancy having to charge it. Currently i have a Bell chime thing not sure what its called looking to take this out wanted to know if i would have to replace it with this https://en-uk.ring.com/collections/accessories/products/din-rail-transformer-gen-2 and this https://en-uk.ring.com/collections/accessories/products/enclosure-din-rail-transformer so basically wanted to confirm if the transformer i mentioned would work with this model
