Editing a branch of the Wiki in the Webinterface

Hi,

we use the internal Wiki of GitLab which is also a git repository.
When i check out the repository of the wiki, i can branch it and work on the branch locally,
however i have not installed a local Wiki (like gollum) so i can only edit it as plain text files.

Is there a possibility to edit a branch (other than main) of the Wiki within the GitLab Wiki-Editor?

Thanks in andvance
