Is my chime compatible?

Recently moved and upon trying to fit our ring (1st gen) doorbell I find that it doesn’t actually trigger the chime in the new house. - the chime is mechanical - it’s a greenbrook DHT01AN-C (apparently the new model name for DHT01A-C) - it has an internal transformer - connecting the ring doorbell doesn’t seem to do anything. The button ring doesn’t light up and the device health report says ‘battery’. Although I’m uncertain if this 1st gen doorbell will say ‘power’ or not. - this chime appears to be listed on the compatible AND incompatible mechanical chime lists. So, my question is: will this chime work or not? I’d prefer to wire the doorbell in so it’ll charge itself and won’t rely on Wi-fi to ring the chime. So if it is in fact incompatible, then I may need to replace it with another chime.
