Is there any way to zoom without holding the RMB key?

In other FPS games is possible to aim and zoom without holding the RMB key, just one click them I can aim and zoom in. But in this game, I see it is impossible to aim and zoom in with 1 click without holding the key. (at least I can’t find the way to do this)
Is it any way to do this?

Tapping RMB lets you aim with the iron sights, but no zoom. Other than that, there’s no specific keybinds for this stuff afaik. But then again, with the huge amount of keybind options, who knows.

you can always tap with the RMB and then press it and keep it pressed, this will give you the toggle aim with zoom.

the issue IS that you need to do that, toggle Zoom mode should be added and judging by the amount of people asking for it they will probably add it soon

If you press RMB then you will get the iron site from a bit far. If you hold it tthen it gives you a little zoom. Maybe try holding left shift to hold your breath. it gives you a little zoom.
