Using Forge Event's encryptedApiTokenId

I’m using the Jira Rest API to modify issues, and am also building a forge application that will listen for events on these issues. My forge app will proxy these events onto another API that I manage.

I’m attempting to understand whether or not each event originated from a change that was made by my REST API.

I noticed in the avi:jira:updated:issue events, that the updates made by my REST client include an encryptedApiTokenId attribute, but I cannot find any information about this attribute.

Would I be able to use this, the contextToken, or any other piece of information on the event to understand who/what triggered the update to the issue?
