"User Manager" role not behaving as expected

[ferret141]

Plan: Business
Hosting: Cloud

Goal: Trying to allow a user to manage user permissions, i.e. invite users and assign roles/groups

Action taken: Placed user in group with permissions to “user management”

Expectation: User can see ‘User Settings’ page and perform administrative actions.

Reality: User can see ‘User Settings’ page but can only suggest users to invite

Is it not possible to grant such permissions or have I potentially missed something fundamental?

Thanks
