I haven’t tried it but if it works the same as a mobile OS you long click to select. Single click to execute.
Edit: apparently that’s not how it works. There is a checkbox on every icon that you have to click directly on the check box to select/unselect.
Don’t forget good hardware too. The switch is an absolutely terrible hand held device. My hands cramp up nearly instantly trying to play on it.
I have purchased BOTW and TOTK for the switch, but I play them on my steam deck with YUZU Waaaay better experience.
