Question about Logitech G PRO X 2 Superstrike

Do I understand this correctly? -The mouse does NOT make a clicking sound on the main buttons, ? because it is triggered optically or by touch sensors? My neighbour always gets chronically disturbed when I play my nervous Starcraft II games. Although I rarely have over 100 APM, it doesn't take long for her to start moving furniture around xD This would be the ultimate solution :):):)
