Hi @imadullakhan!
Could you please elaborate and provide some additional details on what you are trying to achieve?
In general, you can set permissions on every path of the repository, including the /apps hierarchy.
Please keep in mind, that allowing public access to /apps is highly discouraged and in almost all cases not necessary for any valid use case that I have seen in my projects.
Happy to help if you are able to provide some additional details on your requirement.
