@limpid peak You need to install Frigate first. The integration is for connecting an existing Frigate instance to HA. https://docs.frigate.video/frigate/installation
Frigate is a Docker container that can be run on any Docker host including as a Home Assistant Add-on. Note that the Home Assistant Add-on is not the same thing as the integration. The integration is required to integrate Frigate into Home Assistant, whether you are running Frigate as a standalone Docker container or as a Home Assistant Add-on.
