How to disable the possibility to navigate among spaces in anonymous access?

[ffhirata]

Hi all,

I enabled anonymous access of some spaces for different audiences, for instance church, personal projects and family. When I share the link, the confluence pages has the possibility to change to other spaces. Why this possibility? They are different spaces.

What would I expect?
shared link: https://example.atlassian.net/wiki/spaces/SP/overview => for personal projects with my family
shared link: https://example.atlassian.net/wiki/spaces/XY/overview => for projects with my workers

I don´t want that confluence in anonymous access shows all spaces that I have created  and allow navigate among them.
Is it possible to change the menu to avoid navigation among spaces and remove the link in the image of confluence logo?
