Hi and welcome to the EU and UK community. I'm actually waiting for this feature also. The Samsung website does state that this feature has been released in the US and selected European countries, including France, Germany, Italy, the Netherlands, and Poland.
This was posted on the 22nd of October 2024, so hopefully, we won't wait too long for it in the UK.
