Kibaba - Machine learning - access denied

[e101sg]

Dear all,

I am using T-POT (Standard) as VM. Trying to enable the Machine learning features in Kibana ( enabled the 30 day trial license). Can not access the ML feature. (attached the screen shot 1). After some search inside T-Pot , find that elasticsearch.yml in /opt/tpot/docker/elk/elasticsearch/dist .Modified the file as seen in the screen shot 2. Restart the T-Pot but still can not get access. Also can not find the location of kibana.yml. If not mistaken it should be appear in the Analytics page of Kibana. Any inputs helpful.
