Custom Integration entities displayed since 2024.08 - how to give a name

I like the fact thatintegrations not set up from the UI are shown also in the Integrations Overview since 2024.08.

I am using such a custom integration for modbus for a heatpump. The entries now show up, but without beeing assigned to adevice and with the name “Modbus”

How can I define a device and its name for these entities?
