After installation you can control Glass access for every project through a new custom permission, called View Glass Documentation permission.
Content created by glass only shows Users / Groups / Other Actors assigned to Glass View permission.
Administrators can configure Glass View Permission in the Permission Scheme:
Do not use the following user related Dynamic Actors in View Glass permission
Any Custom User picker (single or multi user)
Any Custom Group picker (single or multi group)
Adding any actor above will result the same as adding "Any Application User" - Glass Documentation will be visible for everone.
