I'm not sure whether I am addressing the right section because I don't know whether this is a bug or not. However, I will still describe what I did and seek clarification on a point:

Does a user, who creates a new branch using the GitLab tab, need to be a registered user in OpenProject?

In my case:

* GitLab user is abcd@mydomain.com.
* In OpenProject, this user does not exist.

So my question is, will OpenProject still display all GitLab activities or not?

### Steps to reproduce

1. Setup a account for gitlab, enabled **Show GitLab content.**
2. Create  API Key (from My Account > Access Token)

3. Assigned the GitLab user to Begin of the insertionaEnd of the insertion Begin of the deletion a End of the deletion
4. Enable GitLab module from **Project Settings &gt; Modules &gt;** **GitLab option** (verified by open a work package and the GitLab tab already available)

5. Open Gitlab Repository &gt; Settings &gt; Webhook and add to the URL Begin of the insertion[https://pm.mydomain.com/webhooks/gitlab?key=\[AccessTokenKeyCreatedInStep2\]](https://pm.mydomain.com/webhooks/gitlab?key=%5BAccessTokenKeyCreatedInStep2%5D)End of the insertion Begin of the deletion [https://pm.mydomain.com/webhooks/gitlab?key=\[AccessTokenKeyCreatedInStep2\]](https://pm.mydomain.com/webhooks/gitlab?key=[AccessTokenKeyCreatedInStep2]) End of the deletion
6. Check the trigger:
1. Push Events &gt; All branches
2. Comments
3. Issues events
4. Merge request events
5. Pipline events
7. Save the and see the HTTP 200 response
<img class="op-uc-image op-uc-image_inline" src="/api/v3/attachments/95635/content">
8. Created new branch by using the Git Snippet found in GitLab Tab
`git checkout -b 'epic/519-tạo-django-project-cho-version-2' && git commit --allow-empty -m 'OP#519 Tạo Django Project cho Version 2`
`https://pm.mydomain.com/work_packages/519`
`'`
9. Create some files, push the changes and create merge request &gt; then close the merge request

### What is the buggy behavior?

I can not see any bugs or error here, even check the logs:

here is the log when open work package

<img class="op-uc-image op-uc-image_inline" src="/api/v3/attachments/95640/content">

here is the log when webhook from GitLab posted

<img class="op-uc-image op-uc-image_inline" src="/api/v3/attachments/95641/content">

### What is the expected behavior?

_Describe how the application should behave like. Example:_

1. At step 9 above, the GitLab tab should be show something but still empty
