Gitlab Pages and cookies

I am thinking about hosting my static website using gitlab pages.

The website is completely static, no dynamic contents (besides me updating it from time to time).

Now I am wondering: Since I am in the EU, I have to add a cookie Banner if applicable. Looking at my websites request headers, I can see the following cookie:

I am wondering:

• What does this cookie do?
• Can I disable it somehow?
• If I cannot disable it, do I have to make a cookie banner?

The cookie is actually only send when one is logged into GitLab and contains the authorization information. To remove it:

• make the page public
• if that is not enough, also log out of GitLab
