galaxy_ng api group roles endpoints not functional

Description

The following endpoints on either PAH or galaxy_ng do not work:
api/automation-hub/pulp/api/v3/groups/4/list_roles/
api/automation-hub/pulp/api/v3/groups/4/add_role/
api/automation-hub/pulp/api/v3/groups/4/remove_role/
api/automation-hub/pulp/api/v3/groups/4/my_permissions/

They need access control statements added to each endpoint
believe to be here
https://github.com/ansible/galaxy_ng/blob/master/galaxy_ng/app/access_control/statements/standalone.py

for example we assign access to GroupViewSet but not groups since our app does not use that right now https://github.com/ansible/galaxy_ng/blob/master/galaxy_ng/app/access_control/statements/standalone.py#L402

Key Dependency Versions

{"available_versions":

{"v3": "v3/","pulp-v3": "pulp/api/v3/"}

,"server_version": "4.7.0dev","galaxy_ng_version": "4.7.0dev","galaxy_ng_commit": "","galaxy_importer_version": "0.4.6","pulp_core_version": "3.21.3","pulp_ansible_version": "0.16.0","pulp_container_version": "2.14.1"}

Also tested on
Server version 4.6.2
Pulp Ansible Version 0.15.0
UI Version 4.6.2

Steps to Reproduce

Endpoint: api/automation-hub/pulp/api/v3/groups/4/list_roles/

{"roles": []}

Endpoint:  api/automation-hub/pulp/api/v3/groups/4/add_role/

{"non_field_errors": ["The role does not contain any permission for that object."]}

or

{"users": [],"groups": [],"role": "core.group_creator"}

But this does not add a role

Endpoint: api/automation-hub/pulp/api/v3/groups/4/remove_role/

{"non_field_errors": ["The role does not contain any permission for that object."]}

Endpoint: api/automation-hub/pulp/api/v3/groups/2/my_permissions/

{"permissions": []}

Even though it has 3 roles with over 10 permissions in the GUI.

Actual Behavior

Nothing, nothing is changing

Expected Behavior

The different endpoints should function,
List roles -> lists roles for the group
add_role -> add role to the group
remove_role -> remove role in the group
my_permisions -> ??? same as list?
