How to add inventory data to zabbix?

Question

System administration

There is a d-link 3200 switch. From it, SNMP data comes to the Zabbix server. A data element has been created for the switch to fill in the inventory data field with information about its revision (Filling the host inventory field: Hardware). That is, when you select a switch, you can view its inventory data.
Question: how to add inventory data to the network map where the switch itself is already displayed and data about its name, data on the loading of some ports are added to the signature? That is, so that when viewing the network map, its inventory would be visible in the device signature.
Thanks in advance for a clear answer!
