How to download and install trial license of elasticsearch

Dear sirs,
I want to enable my application to connect Elasticsearch with ODBC, the elastic official say that ODBC client requires a Trial or Platinum license installed, here is the information source Download ODBC Client | Elastic.

In order to test my application, I need to download and install trial license of ES, but I can't find it, anyone please tell me the URL? Thanks a lot.

All you need is to enable the trial license for 30 days from Kibana UI

Thank you very much, problem has been solved.
