How to show collabora menu?

Hi. I am using collabora office in nextcloud 29.0. I’ve noticed that, if I edit the document’s name from within collabora, the application menu (File, Start, Insert, Disposition, References…) shows. But I’ve not found any other way to show it

This is the view before editing the title:

This is the view after editing the title, with the menus shown:

Has anyone found how to show this menus, preferably by default?

Thanks in advance.

What if you close and reopen the document?

The menu is hidden again.

Apparently, it happens only when using the admin user. I created two unprivileged users, and both have the menus when opening a document.
