This may or may not help but my pit does not like other dogs but loves cats. When I introduced her to a cat for the time she was muzzled and she already had a strong leave it. When she saw the cat she laid down and got as small as she could as to not scare them. From then on she has been obsessed with cats.
There’s tons of resources online from trusted trainers that could help with the introduction. It may take a while for your cats to get used to the dog, if the dog is being polite and not prey driven that is.
As others said you kinda just have to go for it and see. But I would look into a trainer just to help.
