Has anyone here sold items on Catawiki? How was your experience?

Hey everyone, I’m selling a few vintage cameras on Catawiki (Nikon Coolpix S2600 (16 MP), Nikon Coolpix S9500 (18 MP), Panasonic Lumix DMC-FX10 (6 MP), Olympus Tough TG-320 (14 MP) - item no. 98288025), but just realized I forgot to set a reserve price. The auction has already started, and I’m not sure what to do now. Does anyone know if it’s possible to adjust it after the auction has begun, or should I just let it run?
