As of now the PM task can only be added by an Administrator, since this is under the Admin portion other users does not have access to the same.
However we have plans in our roadmap to have non admins to have access to create or edit PM Tasks. Please make a note of the Feature ID SDF-45933 for your reference. This will be added into the product in one of our hotfix.
