Sniper zoom toggle possible?

Hi all, I can’t find a way to toggle zoom with scopes. I’d like to just right click and it stays zoomed in until I click it again. I have arthritis and is painful to hold the mouse button down for long periods and I like snipers.

I’ve looked at the option settings but couldn’t find anything. Thanks

Options -> Accessibility -> Weapon ADS -> Toggle

For whatever reason it is in the accessibility menu and not the controls menu. I struggled with finding it too on my first playthrough as zane for probably 10 hours or so.

Doh! Thank you Bob, much appreciated.
