How to add Audit middleware in placement-api

Dear Community !

According to this document (https://docs.openstack.org/keystonemiddleware/yoga/audit.html) It say, I have to add "audit" middleware into api-paste.ini file.

But placement api It not have api-paste.ini and It looks like placement calling middleware in this file (https://opendev.org/openstack/placement/src/branch/master/placement/deploy.p...)

As I understand I have to change some code to use audit middleware ? Or Just create api-paste.ini for placement-api and config wsgi to use this paste ?
