Can I use this action in my workflow?

[gtamas]

A simple question:

The docs say:

Only the pull_request and pull_request_target events are supported. This action does nothing when triggered by other event types

So this means I can't use this in my workflow if it's based push event?

on:
  - push

I created a job here which runs tests, then builds lcov.info data. Can't I simply create another job here that calls this action?
In order to use this action, must I create a job in the pull_request flow?
