Question about Sage the Barista Touch

Difficult to find in Switzerland (for me) you have to look for suitable filter holders and for this version of the touch (first version) they are, unless I'm mistaken, 54 millimetres. I found some on European online sales sites, but you have to look carefully at the description because Sage/Breville (same product) uses a fixing that is not compatible with all other brands' machines. But there are plenty of aftermarkets for this product.
