In how many environments/clusters can I use the non-production license?

Elastic Stack Elasticsearch
1

When I got my Platinum license I got 2 JSON files (a production one and a non-production one).

I understand I can only set the production license in 1 cluster.
But what about the non-production license? I have 3 non production environments/clusters.
Can I define it in all of them?

Thanks!

For this type of questions around licenses I believe it is better that you contact Elastic directly.

I think the question/topic is interesting for others.
Can any one help me?

Thanks!
