How do you open the fuel door on a Kia K5/Optima?

Model: Kia Optima / K5 DL3, MK 5 - Years 2015-2021
Part: Fuel cap

Let's see in this video how to open the fuel door of a Kia K5. This vehicle was known as the Optima in Europe, but it was never imported into the EU under that name. This car has a feature, common to many modern vehicles, where the fuel door opens by pressing on one side, which appears to be lock-free. However, the door must still be opened by a dedicated lock, which is not located, as is commonly the case, near the driver's seat. The button is located on the edge of the remote control, and only by pressing it can the fuel door be opened by pressing on it.
