How can I extract the user and event type of the repository_dispatch?

Hello,

I searched for several days and could not find a way to extract the user that triggered the repository_dispatch event and the event type (or event.action – so confusing) which are marked with the yellow colour in the image.

I need to extract that data using github api or octokit.net for a C# bot. I tried using https://api.github.com/repos/{repoOwner}/{repoName}/actions/runs but it does not return those fields.
