I am testing out a few of the Agent API in RUM with Elasticsearch APM as shown in this documentation here: [Agent API | APM RUM JavaScript agent](https://www.elastic.co/docs/reference/apm/agents/rum-js/agent-api) So far I got most things working like getting span information, traces, transactions, user interactions, errors etc… There’s only one thing left I can’t figure out, and it is how to run the `addLabels`, `setUserContext` and `setCustomContext`. Here’s my code: ```auto Meta Data ``` When I click the `Send Meta Data` button, nothing happens. I look in my browser’s `Network Tab` and no http requests are made. There are no errors in my console, only the message `sent meta data` which shows all the code fired without issues. Am I missing something from my code?
