How to add RuuviTag BLE devices using YAML?

HA got RuuviTag BLE - Home Assistant integration support in December 2022. Unfortunately the auto discovery does not detect all my devices even if I can see them on my phone. Is there a way to manually configure them? There does not seem to be any documentation about this at the moment.

The same devices worked with the old 3rd party integration which only had the manual configuration option (afaik) GitHub - ruuvi-friends/ Ruuvi tag BLE sensor for Home Assistant.
