Is there permissions or policy for using gitlab web-page screenshots

Hi,

We are developing an open source application on GitLab.
We are trying to create Hands-on contents to show users how to use our application.

In part of the contents, we would like to show screenshots of the gitlab web-ui as a cite.
I searched for documents, policies or guidelines that mention screenshots, but could not find what I wes looking for.
(I found one of the following document, but it was for contributors)

Does GitLab have any guidelines or policies concerning the use of screenshots?
I expect something like what Microsoft and Google are showing.

The terms of using the GitLab.com website is available at https://about.gitlab.com/terms/ which carries sections around copyright/IP use, and acceptable use.

Does this help?
