Most doorbell transformers are like 15VA which isn’t really enough for even one unit with a functional chime (not sure about standalone). What’s the capacity of the one you have? Note that 14.5V (38-40VA) transformers sold for security systems are a viable option.
This is worth noting. I have not done this brand, but I did set up one Ring for a client, and his doorbell transformer gave me 16 V open circuit, but did not have enough current to keep the doorbell charged.
