Hey @yannickstruyf3, we are aware of the resource level CRUD operations timeout, the resource why we added as a provider level is because at that time the Terraform provider development documentation is wasn't very clear on how to manage those timeout, so we decided to add it at provider level (global).

Here is more context about the initial implementation:
#20
#42

So we can add it as a feature in a future version of this provider.
