The FormulaShare package includes the permission set FormulaShare Admin User.
Access to the objects, app and tabs for FormulaShare is available to system administrators, and any users with this permission set.
Assign the permission set to users who will configure or monitoring FormulaShare who aren't already full administrators. The permission set is needed for the running users for FormulaShare batch jobs, but isn't needed for users who trigger real time sharing from flows or code.
