Teams in search query if one of the projects has limited access for browsing.

[Veronika]

Hi Community, I have a question related to Teams functionality. 
 I am admin in Jira Cloud premium, we have dozens of projects in Jira, one of them is security sensitive and hidden for all users via Permission Scheme - (Browsing Project Permission is restricted only to Jira admins). It means that when I use 'Team= 20' in a filter - the filter is unavailable for users as one of the projects this filter is automatically applied to is this secret one. I can not limit Teams fields to not to be used by Jira in this secret projects as well. I also tried eliminate this secret project from the search with 'project not in' - still regular users can not use this filter as they don't have access to it. Any ideas?
