How can we use this? Is there any extra button in the interface?

This is about detecting when you start climating through the car or car app while connected to the wallbox. Evcc then enables the charger, see https://docs.evcc.io/en/docs/features/vehicle#air-conditioning.
To enable it, you need to change the soc poll mode of the loadpoint to connected and choose a reasonably low soc poll interval (e.g. 15 minutes), see https://docs.evcc.io/docs/reference/configuration/loadpoints#soc

Please note it might not work with all BMWs, I tested with my i4 and have seen it working with an iX, if your BMW does not provide climating information or provides it differently, it will not work, so I don't know if it works for older cars like the i3.

Thanks, now I understand ;-) I don't know if it's a bug or a feature: In my setting (easee home/BMW iX3 ) it works without this configuration. The reason for this could be that you can configure the Easee wallbox in the location settings so that it always supplies a reserved charging current of at least 6 A (for purposes such as air conditioning). This is actually intended for installations with several wallboxes, but obviously also works (if active) with just one wallbox.
