Project Administrators cannot create or publish projects themselves; they must be assigned projects by Site or Hub Administrators. To assign a project, you must have:
There are two ways to assign projects. You can do it from the project by going to Settings > Advanced and adding the administrator under the Add Project Admin dropdown field.
Another way is to:
Go to Team in the main menu to see your list of administrators.
Select the pen icon to Edit the required team member.
Use the Project access dropdown menu to assign projects. Press Enter after each project they will save automatically.
After assigning the project, you must notify your Project Administrator that they can now log in and start building the project.
