Ring video doorbell transformer question

Hello, I would like to buy a ring video doorbell (1, 2 or 3 not sure but not a PRO) however I'm kinda a noob in the electric world. Currently I have a simple doorbel (Niko 05-540) - 12V, 1A. I have a bell transformer Schneider ITR 8VA. Since my doorbel uses 12V I assume it's configured that my transformer outputs 12V (NOT sure tho). I also live in Europe so I think 8VA should be enough? With my bell there is a classic chime so I figured out I don't need the diode. Preferably I would like to power the doorbell via the existing cables and thus also the chime. I don't mind having 2 sounds in the house. So will my current electric situation be sufficient enough to power the video doorbell?
