When I receive a messageMeEvent from Slack Bolt, the username field is always null.

In messageMeEvent docs, user field exists.

However, in the slack-api-model 1.27.3 version com.slack.api.model.event.MessageMeEvent, there is a username field. I think during the process of deserialization, the field names are different so the mapping is not functioning correctly.

The Slack SDK version

1.27.3

Expected result:

When I receive a messageMeEvent from Slack Bolt, the username field is always null.

Actual result:

I want to get a user id from messageMeEvent
