Does the seagull have a safety seat interface?

Mine is BYD Seagull, version 405. I consulted the 4S store, and they said there was a child safety seat interface (ISOFIX interface). The following are the installation instructions of the child safety seat sent to me by the 4S shop:

The child safety seat interface (vertical opening) can be found in the rear seat hip position of 1. There is a circular safety seat interface sign next to the opening.

There is an optional safety seat binding ring slightly below the seat belt hook. You can usually find it along the seat belt.

There is also a binding port in the back seat.
