multi tenants Gateway sharing

Greetings.
I need help.

LNS ChirpstackVersion: v4.14.0
Installation was performed from the repository using the standard methods described in the manual.
The server is configured and running, running without errors… BUT

The multitenants architecture was chosen for the network. Accordingly, there is one infrastructure tenant, the owner of all gateways, and there are several independent services under separate tenants.
It was not possible to make the gateways available to other tenants as well.
There are no controls for GW Sharing anywhere in the web interface.
The corresponding network policies are not enabled via the API, moreover, there is no network_policy table in the database.
Can you tell me what the problem is, where to look and what to read?
Thank you.
