Can Orchestrator with trial Licence see and manage robot license?

I’m now using Orchestrator with trial License for PoC. I read that Robot license files can be uploaded from local PC to Orchestrator and are able to be managed on Orchestrator. But I can’t do that with the Orchestrator. Even can’t find the License Tab on setting page(I saw there is the License tab on UiPath Academy). Is it because I use the trial licensed Orchestrator?
