Different access tokens for the same user account across domains

Description
Apologies if this is not the correct usage for this.

An application I am working on for my company wants to use the zoom api to help clients who are using zoom in their school. I have done some testing do what we want but I came across a problem that I am unsure on how to solve. I will do my best to describe it.

I have an OAuth application setup with zoom that I intend to publish with its development and production credentials:
production:
client_id: abcdef
client_secret: secret

I have 3 subdomains that we control that each have their own database and do not talk with each other.
https://foo.example.com/
https://bar.example.com/
https://fizz.example.com/

a user by the name of steve has access to foo and bar. he logs into foo with his one zoom account and everything is fine. now when he tries to go into bar and setup his zoom account there he gets an error.

is it possible for steve to login into his zoom account on foo and bar and receive an access token for both. my current assumption (from what I have found / read) is no and that the zoom access tokens would need to be shared between the two subdomains if they are using the same client_id.

Which App Type (OAuth / Chatbot / JWT / Webhook)?
OAuth
