Share security groups between projects

Hello,
Is it possible to share security groups across projects ?
I saw on this topic that it was possible to share a private network between two projects :
https://community.ovhcloud.com/community/en/private-network-shared-between-two-or-more-public-cloud-projects?id=community_question&sys_id=9a46b98c585e42d02d4c51cec5fc9662

I tried these commands to share a security group between my two projects
https://docs.openstack.org/neutron/latest/admin/config-rbac.html#sharing-a-security-group-with-specific-projects

openstack network rbac create --target-project xxxx --action
access_as_shared --type security_group yyyy

The previous command returns no error but whenever I try to show my shared security groups with

openstack security group list

...there is nothing displayed.
This is probably due to my openstack user rights.

Is there a solution to share security groups between projects ?

Thanks for your help.
