Access to data is by index. If you grant a role access to an index then they have access to all of that index. To control access, each team's application logs should be in separate indexes and each team given access only to the index containing their data.
You may be able to find a workaround using search filters. Each team (role) would be configured with a search filter that only returns data pertinent to that team. If you try this be aware that search filters can be bypassed and often have undesired side-effects.
