2020 Connected E3 buckle change

Hello,
Does anyone know if the buckle is removable from the rubber strap of the Connected 2020, and how?
I have a grey titanium Connected and I would like to get a second rubber strap, but I expect that the accessory straps will be coming with the stainless steel buckle that doesn't match my titanium case. TAG Heuer also sells separately a grey titanium buckle, so there should be a way to remove the steel buckle from the strap and swap it for the titanium one, but I just cannot figure out how. On one end it seems firmly attached. Maybe it can be done only by a professional?

Hi
It's removable similar to a spring bar.
Releases the rubber.
A springbar tool will do the trick.

If TAG Heuer sells buckles separately (both in gray and black titanium), they must be able to be changed on the strap. They do not have a quick release system like the Gen2 Modular, but they must be able to be removed with the help of a tool such as those for removing standard watch straps

Thank you! I hope it's a spring bar. It looks very stiff and unmovable.
(update; yeah, I think it's a spring bar. I pushed the rubber away and saw it a bit better. Cheers!)
