Pro on-prem license with multiple environments

I'm interested in running Metabase on AWS under the pro on-prem license. Our stack is set up so that we have multiple environments (dev, qa, prod, etc.) and each would have its own separate Metabase instance. Although only the prod instance will be relevant for end-users, we want non-prod instances to be available for integration testing.

Does a single license allow for this setup? Is the license keyed to a specific AWS organization ID or some other identifier?

A single Metabase license is valid for all the environments you want, we’ll only charge for the sum of users you have in all those environments
